| 英文摘要 | a novel lower critical solution temperature (lcst) membrane forming system containing cellulose acetate (ca)/poly (vinyl pyrrolidone) (pvp 3 60k)/n-methyl-2-pyrrolidone (nmp)/1,2-propanediol with a weight ratio of 24.0:5.0:62.6:8.4 had been developed. ca hollow fiber ultrafiltration (uf) membranes were fabricated using the dry-wet spinning technique. the fibers were post-treated with a 200 mg/l hypochlorite solution over a period of 6 it at ph 7. the experimental results showed that water flux of a membrane decreased while retention increased with increasing ca concentration in a dope. it was concluded that the membrane pore size decreased with increasing ca concentration. the membrane fouling tendency for bsa was 3 times higher than that for pvp 24k.
