Preparation of resin filled ethylene vinyl alcohol copolymer hollow fiber membrane
Li Hong · Tianjin Gongye Daxue xuebao · 2008
Using ethylene vinyl alcohol copolymer(EVAL) as membrane matrix material,anion exchange resin D301R as functional particles,resin filled EVAL hollow fiber membrane are prepared by dry-wet spinning process.The effects of temperature of coagulation bath and concentration of EVAL on pure water flux and rejection of BSA are discussed.The experimental results show that the resin filled EVAL hollow fiber membrane is possessed of high water flux and BSA retention rate,when the concentration of EVAL,concentration of ion exchange resin in the casting solution and coagulation bath temperature are 18%,24% and 40-50 ℃ respectively.
