AB  - The objective of the present study was to determine the impact of cadmium (Cd) concentration in the soil on its uptake by tobacco plants, and to compare the ability of diverse extraction procedures for determining Cd bioavailability and predicting soil-to-plant transfer and Cd plant concentrations. The pseudo-total digestion procedure, modified Tessier sequential extraction and six standard single-extraction tests for estimation of metal mobility and bioavailability were used for the leaching of Cd from a native soil, as well as samples artificially contaminated over a wide range of Cd concentrations. The results of various leaching tests were compared between each other, as well as with the amounts of Cd taken up by tobacco plants in pot experiments. In the native soil sample, most of the Cd was found in fractions not readily available under natural conditions, but with increasing pollution level, Cd amounts in readily available forms increased. With increasing concentrations of Cd in the soil, the quantity of pollutant taken up in tobacco also increased, while the transfer factor (TF) decreased. Linear and non-linear empirical models were developed for predicting the uptake of Cd by tobacco plants based on the results of selected leaching tests. The non-linear equations for ISO 14870 (diethylenetriaminepentaacetic acid extraction - DTPA), ISO/TS 21268-2 (CaCl2 leaching procedure), US EPA 1311 (toxicity characteristic leaching procedure - TCLP) single step extractions, and the sum of the first two fractions of the sequential extraction, exhibited the best correlation with the experimentally determined concentrations of Cd in plants over the entire range of pollutant concentrations. This approach can improve and facilitate the assessment of human exposure to Cd by tobacco smoking, but may also have wider applicability in predicting soil-to-plant transfer.

AB  - This paper presents the results of determining the pseudo-total concentration of five heavy metals in the soil on which the destruction of ammunition, mines, and explosive devices is carried out by the method of open detonation. In the analyzed area, the concentrations of cadmium, lead, nickel, copper, and zinc were determined, while from the physical properties of the soil were determined the granulometric composition and the pH. The aim of the study is to determine the origin and total load on heavy metals and, based on that, to assess the dangers and impact of the site in terms of the soil pollution by heavy metals. In accordance with the regulations of Bosnia and Herzegovina, the results of the soil testing showed a significant load of copper (up to seven times) and cadmium (up to six times), and exceeding the allowed values for nickel and zinc in some places. Lead was the only metal whose concentration was within the maximum allowed and according to that the soil was classified as unpolluted. A sample of soil from the edge of the pit is the only sample in which all heavy metals, except Ni, were within the maximum allowable concentration. In regard to the concentration of the examined metals, the soil of the pit is classified as medium polluted from the aspect of copper, cadmium, and nickel and highly contaminated with zinc. The concentrations of copper and zinc in the examination area correspond to contaminated soil that represents ecological risk, which requires soil remediation.

AB  - Fluorapatite nanopowders with different amounts of fluoride ions were prepared using the surfactant-assisted microwave method under isothermal conditions. Microwave irradiation was applied for the rapid formation of crystals. A micellar solution of polyoxyethylene (23) lauryl ether was used as a regulator of nucleation and crystal growth. Characterization studies from X-ray diffraction, field-emission scaning electron microscopy and Fourier(-)transform infrared spectra showed that crystals have an apatite structure and particles of all samples are nano size, with an average length of 50 mn and about 15-25 nm in diameter. Antimicrobial studies have demonstrated that synthesized fluorapatite nanopowders exhibit activity against tested pathogens: Eseherichia coli, Staphylococcus aureus and Candida albicans. Activity increased with the amount of fluoride ions. The synthesized fluorapatite nanomaterials are promising as materials in environmental protection and medicine for orthopedics and dental restorations.

AB  - As a result of the destruction of ammunition, mines, and explosive devices by the method of open detonation, the increased concentration of heavy metals is often recorded in the soil of military polygons, which is a serious ecological problem. However, in order to determine the potential risk of such locations to the environment, it is necessary to determine, in addition to the total content, the forms in which the metals are present. In this paper, a sequential extraction method was used to analyze the six fractions of five heavy metals (cadmium, lead, nickel, copper, and zinc) in the soil of the polygon for destruction of ammunition, mines, and explosive devices. Samples were collected from the place of direct detonation (so-called pits) and from the edge of the pit. The aim of this research is determination of metal speciation in order to obtain a better insight in their mobility and risk arising from this. The results showed that heavy metals are predominantly present in the residual, oxide, and organic fractions. Cd and Cu were also significantly present in the mobile fractions due to conducted activities on the polygon. To assess the potential environmental risk of soil, the risk assessment code (RAC) and individual (ICF) and global (GCF) contamination factors were used. According to the RAC, the mobility and bioavailability of the analyzed heavy metals decreases in the following order: Cd  gt  Cu  gt  Zn  gt  Pb  gt  Ni. ICF results show low to moderate risk, while GCF results show low risk in terms of heavy metal contamination in the examined area.

AB  - Red mud, a heterogeneous mineral waste from aluminum industry, can be beneficially utilized as a sorbent. High alkalinity and the amount of water soluble ions can limit some of its applications. This study's aim was to explore and correlate physicochemical properties and sorption efficiencies of acid treated red mud. Sorbents (BRM0.05-BRM1), obtained by varying HCl concentration (0.05-1 mol/L), were characterized in terms of mineralogical composition, surface functional groups, electrical conductivity (EC) and the point of zero charge (pH(PZC)). Removal of Ni(II) ions was tested in batch conditions. Sorbents EC and pH(PZC) values decreased with the increase of acid concentration. Structural analysis revealed that sodalite and calcite phases were completely lost starting from the samples BRM0.25 and BRM0.5, respectively. Along with the sodalite dissolution, gibbsite precipitation was observed. Ni(II) sorption increased with the increase of initial pH from 2 to 4, while at pH  gt 4 it depended only on sorbent material. A radical drop of maximum sorption capacities was associated with the increase of acid concentration to 0.25 mol/L, whereas additional rise to 1 mol/L caused minor fluctuations. Fully loaded sorbents BRM0.25-BRM0.1 also exhibited considerable lower stability over a range of investigated pH conditions. Dissolution of sodalite and calcite, and the consequent reduction of buffering capacities can be identified as the main reasons for decreasing sorption efficiency. Sample BRM0.05 was efficient in terms of both sorption and stability, yet environmentally more benign than the original red mud due to the lower alkalinity and content of water soluble ions.

AB  - The removal of Ni(II) from aqueous solutions by raw red mud powder was studied in the absence and in the presence of citrate ligand, as a function of process parameters. Using lower initial Ni(II) concentration (10(-3) mol/L) detectable amounts were found only at initial pH 3, whereas for higher concentration (2 x 10(-3) mol/L) removal increased simultaneously with pH in the range 3-4 and at pH  gt  8. Process efficiency was suppressed in the presence of citrate. However, at Ni/Citrate molar ratios 1:0.25 and 1:0.5, 10-20% decrease was noticed in acidic media, while the negative influence diminished with the rise of pH. At higher ligand rates, formation of stable aqueous complex between Ni(II) and citrate significantly reduced metal removal in the whole tested initial pH range (3-10). Due to instantaneous pH rise above 8, removal of Ni(II) from 10(-3) mol/L solution was completed in 5 min. Kinetic data demonstrated slower Ni(II) uptake using both solutions of higher initial Ni(II) concentrations and Ni/Citrate solutions. At initial pH 5, estimated capacity towards Ni(II) was found to be 27.4 mg/g, without citrate. For Ni/Citrate molar ratios 1:0.25 and 1:0.5, capacities decreased slightly to 25 mg/g and 21 mg/g, whereas at equimolar and higher concentrations, citrate significantly inhibited Ni(II) immobilization (7.6 mg/g and 2.5 mg/g, respectively for Ni/Citrate ratios 1:1 and 1:2). The results demonstrated beneficial effect of red mud high alkalinity on Ni(II) removal. The sorbent satisfactorily immobilize nickel from solutions having initial Ni/Citrate molar ratios lower than 1:1, and neutral to alkaline initial pH. FUR analysis confirmed that red mud can act as a removal agent for Ni(II), Ni/Citrate complex and free citrate ligand.

abstract = "The removal of Ni(II) from aqueous solutions by raw red mud powder was studied in the absence and in the presence of citrate ligand, as a function of process parameters. Using lower initial Ni(II) concentration (10(-3) mol/L) detectable amounts were found only at initial pH 3, whereas for higher concentration (2 x 10(-3) mol/L) removal increased simultaneously with pH in the range 3-4 and at pH  gt  8. Process efficiency was suppressed in the presence of citrate. However, at Ni/Citrate molar ratios 1:0.25 and 1:0.5, 10-20% decrease was noticed in acidic media, while the negative influence diminished with the rise of pH. At higher ligand rates, formation of stable aqueous complex between Ni(II) and citrate significantly reduced metal removal in the whole tested initial pH range (3-10). Due to instantaneous pH rise above 8, removal of Ni(II) from 10(-3) mol/L solution was completed in 5 min. Kinetic data demonstrated slower Ni(II) uptake using both solutions of higher initial Ni(II) concentrations and Ni/Citrate solutions. At initial pH 5, estimated capacity towards Ni(II) was found to be 27.4 mg/g, without citrate. For Ni/Citrate molar ratios 1:0.25 and 1:0.5, capacities decreased slightly to 25 mg/g and 21 mg/g, whereas at equimolar and higher concentrations, citrate significantly inhibited Ni(II) immobilization (7.6 mg/g and 2.5 mg/g, respectively for Ni/Citrate ratios 1:1 and 1:2). The results demonstrated beneficial effect of red mud high alkalinity on Ni(II) removal. The sorbent satisfactorily immobilize nickel from solutions having initial Ni/Citrate molar ratios lower than 1:1, and neutral to alkaline initial pH. FUR analysis confirmed that red mud can act as a removal agent for Ni(II), Ni/Citrate complex and free citrate ligand.",

AB  - The waste red mud, remaining in remarkable quantities after the digestion of bauxite ores following the Bayer process, contains number of voluble minerals with excellent sorption properties towards aqueous heavy metals. Heating at 600 degrees C was found to be a favorable treatment for revalorization of rinsed red mud into an efficient Ni2+ sorbent (RBRM600). As potential practical application of RBRM600 for Ni2+ accumulation greatly depends on the solution composition and pH, the influence of these vital process variables was considered in this study. The initial pH rise from 2 to 3.5 caused the most evident increase in the amounts of Ni2+ removed: furthermore, the effect was more obvious for lower initial sorbate concentrations. Conversely, changes of the solution pH between 3.5 and 8 did not have a significant influence on the sorption. The increase of initial cation concentration caused the increase of the sorbed amount. following Langmuir isotherm model. The calculated maximum sorption capacity of 27.54 mg/g demonstrated capacity increase of approximately 20% in respect to inactivated rinsed red mud. Coexisting cations inhibited Ni2+ removal in the following order: Cu2+  gt  Pb2+  gt = Zn2+  gt  Cd2+  gt  gt  Ca2+, whereas the presence of Na+ and K+ did not affect the process. The investigated anions caused decrease of Ni2+ removal efficiency in the order: EDTA  gt  chromate  gt  acetate  gt  sulphate, however, fluoride slightly improved sorption. Low desorption of Ni2+ in various media showed that the heavy metal cations are tightly bound to RBRM600 surface, thus disposal or reuse of spent sorbent should be considered.

AB  - Red mud, an abundant industrial waste from alumina industry, represents a rich source of various metal oxides, mainly of Fe2O3 Al2O3 and SiO2. In this study, the rinsed Bosnian red mud (RBRM) was evaluated as an economical, composite sorbent for aqueous Ni2+ ions. The process was investigated as a function of pH, contact time and initial metal concentration. The investigated mineral mixture exhibited a high acid neutralising capacity, and its most important role in cation immobilization was observed in the initial pH range 2-8. The initial metal ion concentration strongly influenced the sorption kinetics and equilibrium times. Addition of 5 g/L of RBRM caused 100% removal from the solutions of 10(-4) to 5 x 10(-4) mol/L, whereas with the further increase of Ni2+ concentration to 8 x 10(-3) mol/L, the removal efficiency decreased to 26%. The maximum sorption capacity of 0.372 mmol/g, at initial pH 5, was determined using Langmuir theoretical model. The possibility of sorption efficiency improvement by annealing RBRM powder was investigated in the range 200-900 degrees C and the relationships between temperature, red mud physicochemical and sorption properties were established. The optimum heating temperature was found to be 600 degrees C, due to water exclusion from gibbsite and bayerite phases, leading to improved porosity and surface area, as well as increased pH value and sorption efficiency. The stability of the sorbed cation was assessed by leaching experiments in distilled water and acidic TCLP2 solution.
