| 摘 要： | 采用具有亲水性的乙烯-乙烯醇共聚物(EVAL)作为纤维吸附剂基质材料,粉末型Lewatit阳离子交换树脂CNP80ws为功能材料,采用可控相分离方法,制备了不同表面形态结构的树脂填充EVAL吸附剂.当使用外部液体调控相分离过程时,在纤维的表面形成了粗糙的开孔结构,并且随树脂的填充量提高纤维表面的粗糙度与开孔度有所提高.研究结果表明:树脂填充EVAL纤维吸附剂具有较大的吸附容量与较高的脱附率,其吸附容量不低于53.9mg BSA/g吸附剂(树脂填充量50%).

| Abstract: | In order to reduce non-specific adsorption caused by hydrophobic attraction, the hydrophilic polymer EVAL was chosen as the fiber substrate to form matrix of fiber adsorbents. Incorporated with resin powder in fiber matrix, the resin CNP80ws filled EVAL fibrous adsorbents with some extent of open pore on its surface were prepared by the method of controlled phase transition with some external liquids. The more open structure on its surface was obtained with higher resin loading. The behavior of adsorption and desorption with model protein BSA was studied. The results showed that the resin CNP80ws filled EVAL fibrous adsorbents had good adsorption capacity and desorption. The adsorption capacity of resin CNP 80ws filled EVAL fibrous adsorbents were in the range of 53.9~54.8 mg BSA/(g adsorbent) (50% resin loading). |
