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  - Antimicrobial materials based on hydroxyapatite are potentially attractive in a wide variety of medical applications. The synthesis of copper and zinc-doped hydroxyapatite was done by neutralization method. This method consists of dissolving CuO or ZnO in solution of H3PO4, and the slow addition to suspension of Ca(OH)(2) for obtaining monophasic product. Characterization studies from XRD, SEM, TEM and FTIR spectra showed that particles of all samples are of nano size and they do not contain any discernible crystalline impurity. The quantitative elemental analysis showed that the copper and zinc ions fully incorporated into the hydroxyapatite. The antimicrobial effects of doped hydroxyapatite powders against pathogen bacterial strains Escherichia coli, Staphylococcus aureus and pathogen yeast Candida albicans were tested in solid and liquid media. Quantitative test in liquid media clearly showed that copper and zinc-doped samples had viable cells reduction ability for all tested strains.

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.

AB  - The adsorption of a zeolite, clay and diatomite from Serbia toward aqueous Cu2+ ions was studied, at different pH. The adsorbents were characterized with respect to phase composition, specific surface area and point of zero charge. The amounts Of Cu2+ removed from the solution, increased with increasing initial pH, reaching nearly 100% at pH GT 7, regardless of the adsorbent type and metal concentration, due to precipitation of Cu(OH)(2). Relatively constant final pH values and less significant increase Of Cu2+ uptake observed in the initial pH range 4-6 have pointed out the role of buffering properties of investigated adsorbent materials. The maximum adsorption capacities decreased in the order zeolite (0.128 mmol/g) GT clay (0.096 mmol/g) GT diatomite (0.047 mmol/g). The Langmuir equation was most suitable for data fitting. The proportion Of Cu2+ desorbed in acidic media decreased with the increase of previously adsorbed amounts by zeolite and clay, while the opposite was true for diatomite. Ion exchange of exchangeable cations and protons were identified as main adsorption mechanisms, with latter being most apparent in the removal mechanism of diatomite. Considering low-cost, local availability and environmentally friendly materials, zeolite exhibited highest potential for environmental and health protection applications. (C) 2008 Elsevier B.V.
