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 CNP80ws filled EVAL fibrous adsorbents were in the range of 53.9-54.8 mg BSA/(g adsorbent) (50% resin loading).
