摘要: 壳聚糖-聚砜酰胺复合膜在干、湿情况下,其富氧性能存在明显的差别[1],表明壳聚糖是较好的富氧材料。从壳聚糖的结构可看出,它能通过氨基、羟基与许多重金属离子形成螯合物[2],这种螯合物与低分子氧载体[3]的结构相似.本文在壳聚糖-聚砜酰胺复合膜上固定金属钴盐,并在干、湿两种状态下测定了其富氧性能的差别。

Abstract: The composite membranes of chitosan containing cobalt salt as the fixed oxygen carriers and polysulfone amide were obtained.The damp membrane can enrich oxygen from air,while dry membrane cannot.The effects of temperature,operating pressure and cobalt salt concentration on the behaviour of damp membrane were reported.
