摘要：
The purpose of this research was to investigate the efficiency of the sorption of copper (II) ions on biopolymeric materials. Blends between poly (vinyl alcohol) [PVA] (DH=98%, DP=900) as a synthetic polymer and scleroglucan (Sclg) as a natural biopolymer have been prepared by repeated freezing-thawing cycles. The sorption capacity of the cryogel against Cu2+ ions has been determined by VIS Spectroscopy. The alteration of the PVA cryogel properties by Sclg addition and by Cu2+ ions sorption has been investigated by FTIR Spectroscopy. The highest efficiency in Cu2+ ions sorption has been obtained for cryogels containing scleroglucan (Sclg) and poly(vinyl alcohol) (PVA) in 1:9 weight ratio by comparing to pure PVA cryogels.
