AB  - The possibility of retaining Cs+ and Co2+ bound by immobilization processes in the cement matrix is defined as the subject of its investigation: the cement matrix formulation, the water/ cement ratio, the amount of waste, and the porosity of such a structure. Implementing the standard leaching method by Hespe the possibility of comparing different authors’ results was achieved. Diffusion and semi-empirical model were used to investigate the transport phenomenon in order to predict the leaching level for a long period of time. Leaching of Co2+ and Cs+ ions under dynamic conditions immobilized in the cement matrix dynamic conditions decreases with the increase of the sludge content, regarding porosity increase. The effects of the diffusion and surface washing are equalized, and the contribution ofthe matrix dissolution to the Cs + and Co2+ transport in the cement porous media increases, on average, for one order of magnitude. The semi-empirical model gives a better approximation for Co2+ and Cs+ leaching process for the duration ofthe experiment while both models significantly approximate leaching results in dynamic conditions. © 2019, Vinca Inst Nuclear Sci.

AB  - The use of soil additives for toxic metals chemical stabilization aims to decrease in situ the pollutants' mobility and availability. In this study, the effectiveness of rinsed red mud (RBRM) and annealed animal bones (B400) was compared in terms of Cu, Pb and Ni stabilization in two contaminated soils with contrasting properties Dystric Cambisol (CM dy) and Rendzic Leptosol (LP rz). The mobility of metals in unamended soil samples (control) and samples amended with 1% and 5% of selected additives were compared using sequential extraction protocol. The relative content of metals in readily and potentially available fractions was higher in CM dy (62% Pb, 13% Cu, and 31% Ni in exchangeable fraction) than in LP rz ( lt  5% of Pb, Cu, Ni in exchangeable fraction). In CM dy, both additives have caused a decrease in metal mobility with an increase of their doses. The effect of 5% sorbent addition was most pronounced related to Pb immobilization, provoking decrease of exchangeable Pb content to  lt  10%. Furthermore, B400 addition has redistributed investigated metals from the exchangeable to the residual phase more effectively than RBRM, and its effect on metal mobility decreased in the order Pb  gt  Cu  gt  Ni. Amending of LP rz soil had limited effects with no apparent decrease in exchangeable metal content. The effects of soil type variation, the type of additive and the additive dose onto metal mobility were compared according to ANOVA results. The content of readily and potentially available forms of metals was found to be (i) significantly correlated with all investigated variables for Pb, (ii) significantly correlated with soil type for Cu, and (iii) not in significant correlation with selected variables for Ni. Complex impacts of soil properties and treatment conditions on the mobility of co-contaminants emphasize the need for an individual approach to each case of contamination.

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  - The sorption properties of waste facade, brick, and asphalt sample towards Sr(II), Co(II), and Ni(II) ions from single and multicomponent solutions were investigated. The highest sorption capacity was found for Ni(II) ions, while the most effective sorbent was facade. Simplex Centroid Mixture Design was used in order to investigate the sorption processes of ions from solutions with different composition as well as the competition between the cations. Based on the statistical analysis results, the equations for data modeling were proposed. According to the observations, the investigated solid matrices can be effectively used for the liquid radioactive waste treatment. Furthermore, the applied methodology turned out to be an easy and operational way for the investigations of multicomponent sorption processes.

AB  - The interaction between Sr2+ ions and variously treated animal bones was studied from the aspect of Sr-90 isotope immobilization from the contaminated effluents. As a source of biogenic, poorly-crystalline apatite, bone based materials, in general, were found to exhibit good retention properties towards Sr2+ cation. Furthermore, sorption capacities of H2O2 treated bone sample and sample annealed at 400 degrees C were found to be higher in respect to a commercial bone char and synthetic hydroxyapatite. Mentioned treatments induced partial organic phase removal from the pores of the skeletal material that caused the increase of the specific surface area. Higher temperatures provoked an increase of the apatite phase crystallinity, agglomeration of nano-crystals and a decrease of both the specific surface area and Sr2+ sorption. The immobilization was pH independent in the range 4-10, as a result of sorbents buffering properties. Kinetic data were well represented by the pseudo-second-order reaction model. Sorption isotherms were in better correlation with Freundlich than Langmuir theoretical model, whereas samples heated at 800 degrees C and 1000 degrees C showed S-type isotherms which were in a good agreement with sigmoidal Langmuir equation. The ion-exchange with Ca2+ cations and the specific cation sorption were two recognized mechanisms in the Sr2+ removal process, with relative contributions strongly dependent on the sorbents physicochemical properties. Sr2+ -loaded products were the most stable in the neutral and alkaline environments, while Ca2+ containing and acidic leaching solutions caused increased Sr2+ desorption. (C) 2010 Elsevier B.V.

AB  - The objective of the present study was the evaluation of differently treated bovine bones for Co2+ removal from aqueous media. Powdered bones (B), as well as samples prepared by H2O2 oxidation (BH2O2) and annealing at 400-1000 degrees C (B400-B1000), were tested as sorbent materials. A combination of XRD, FTIR spectroscopies, DTA/TGA analyses, specific surface area (S-p) and point of zero charge (pH(PZC)) measurements was utilized for physicochemical characterization of sorbents. Sorption of Co2+ was studied in batch conditions as a function of pH, contact time and Co2+ concentration. Initial pH values in the range4-8 were found optimal for sorption experiments. Equilibrium time of 24 h was required in all investigated systems. The maximum sorption capacities differ significantly from 0.078 to 0.495 mmol/g, whereas the affinity towards Co2+ decreased in the order: B400 GT BH2O2 GT B600 GT B GT B800 GT B1000. The pseudo-second-order model and Langmuir theoretical equation were used for fitting the kinetic and equilibrium data, respectively. Ion-exchange with Ca2+ and specific cation sorption were identified as main removal mechanisms. The amounts of Co2+ desorbed from loaded bone sorbents increased with the decrease of pH as well as with the increase of Ca2+ concentration. Heating at 400 degrees C was found to be an optimal treatment for the production of the Co2+ removal agent. (C) 2008 Elsevier B.V. All rights reserved.
