“…Hydroxyapatite (HA, Ca 10 (PO 4 ) 6 (OH) 2 ) has been identified as a promising material and an efficient adsorbent for the remediation technologies because of its high sorption capacity, biocompatibility, availability and low cost, high stability non-toxicity, and chemical inertness [9]. However, our previous studies have showed that hydroxyapatite has poor mechanical properties, used in the form of a fine powder dispersed in an aqueous solution.…”

“…Our studies revealed that hydroxyapatite can be blended with alginate to overcome the deficiencies of hydroxyapatite and to combine the good characteristics of these two kinds of biomaterial. Beside this, adsorbents combining with magnetic properties are one of the most promising technologies, providing an efficient, fast and economical method for separation and remediation studies [9]- [10].…”

Abstract-Biopolymers materials can be used for many applications in various areas. In this study, prepared magnetic alginate/hydroxyapatite biopolymeric composites were used for removal of europium from aqueous solution. In this respect, the physicochemical parameters of adsorption process are investigated for optimum uptake conditions. Sorption mechanisms will be investigated using experimental results and calculated parameters from some models as thermodynamic, isothermal and kinetic. The results suggest that these materials were proven to be potent material with chemical adsorption mechanism for reducing the concentration of europium with high efficiency in aqueous solution. Due to the high sorption capacity as 250.0 mg/g of the prepared material, plus its easy preparation process, economic advantage and environmental friendly nature would make these composites a promising removal and recovery agent for lanthanides.
