摘　　要：本文采用反相聚合的方法以戊二醛为交联剂合成了珠状交联聚乙烯醇凝胶，并研究了它对胆红素的吸附性能。结果表明交联聚乙烯醇对胆红素的体外吸附率受到吸附剂的交联度、颗粒直径、溶液中白蛋白的浓度、吸附温度及离子强度的影响。该类吸附剂对胆红素具有良好的吸附动力学性能。This paper reported the adsorption of bilirubin in vitro on cross-linked polyvinylalcohol gel. The results showed that the adsorption efficiency affected not only by the crosslinking degree, the size of particle and the ratio of the bilirubin to the albumin, but also by the adsorption temperature and the ion strength. This kind of adsorbent possesses a good adsorption dynamic characteristics.
