Abstract

Abstract: Anew adsorbent for bilirubin was prepared by immobilizing guanidine on cross-linked polyvinyl alcohol gel. It possesses good adsorption performance for bilirubin both in albuminfree and albumin solutions. The adsorption efficiency increases with the decrease of the crosslinking degree of PVA, the ratio of albumin to bilirubin and ion concentration. The increase of the guanidine amount can improve the adsorption performance.

Key words: Guanidine, Cross-linked polyvinyl alcohol, Bilirubin, Adsorbent
