Cation-exchange hollow fiber membrane was prepared by radiation-induced grafting polymerization of styrene onto polyethylene hollow fiber membrane and its sulfonation. Adsorption characteristics for the cation-exchange membranes are examined when the solution of Co 2Ο© permeates across the cation-exc

Two modified hollow fiber membranes, the chelating hollow fiber membrane with iminodiacetic acid and the cation-exchange hollow fiber membrane with sulfonic acid group (OSO 3 H), were prepared by radiation-induced grafting of glycidyl methacrylate onto polyethylene hollow fiber membrane and its subs
## Abstract Acrylic acid and sodium styrene sulfonate were grafted onto highβdensity polyethylene (HDPE) membrane by preirradiation, and we prepared a cation exchange membrane with strong acid and weak acid groups. The HCl was used as an additive to change the pH of grafting system, and the effect
