Sorption Properties of Materials Based on Polyvinylpyrrolidone Copolymers

Sorption properties of polyvinylpyrrolidone copolymers regarding to different acid-base indicators, as well as heparin and iodine have been investigated. The amount of sorption active centers of synthesized copolymers depends upon synthesis conditions, namely upon temperature and initiator amount, and is determined by the nature of sorbates and copolymers functional groups.

Physico-Chemical and Sorptive Properties of Nanocomposites Based on Zirconium Oxide

Nanocomposites “activated carbon–zirconium(IV) oxide” were synthesized by homogeneous precipitation. The obtained samples were characterized by X-ray analysis and electron microscopy. The chemical composition of the nanocomposites was determined by the thermal analysis. Sorption properties were determined. The degree of phosphate ions removal was almost 97 %.
