Документ Sorption properties of hydroxyapatite-based composites in alginate shell(2018) Yanovska, Ganna; Bolshanina, Svitlana; Ivchenko, Viktoriya; Sydorenko, Yaroslav; Ponomarova, LudmylaHydroxyapatite-based composite materials are widely used for treatment of bone defects due to their biocompatibility and osteoconductivity. In this work they were successfully combined with alginate – biopolymer with gel forming ability. Sorption properties of the composite materials towards Cu2+ and Zn2+ions were compared. It was shown that sorption of Zn2+ ions is more effective due to ion exchange properties and formation of new insoluble phase after contact with microsphere surface.
