简介:在现在的学习,我们准备了macroporous聚乙烯化合物的白酒祷告。一系列bilirubin吸附物被八个胺代理人的固定作为ligands产生到祷告。bilirubin的吸附被评估由在vitro静态、动态的吸附测试。结果证明这些吸附物有优秀吸附效率和能力。在八ligands,trimethylamine(TMA),triethylamine(茶)和1,6-hexanediamine之中()显示出最高的吸附能力。吸附平衡能在半个小时被完成,并且bilirubin的吸附百分比直到80%。静态的电和恐水病的相互作用在bilirubin吸附起了主要作用,并且吸附被发现匹配单层模型。这些吸附物的优秀吸附在临床的处理显示他们的潜力。
