摘要
明胶(Gelatin)曾用于与其它高聚物共混制备分离膜材料,但迄今未见单独成膜用于膜分离的报道.本文首次报道高纯牛骨胶经Cr_2(SO_4)_3交联后制膜的方法,并成功地用于醇/水渗透蒸发分离.采用渗透蒸发分离醇/水混合物,既节能又简便.
After cross-linked by using Cr2(SO4)3, gelatin membrane was used successfully for separation of ethanol/water mixture by pervaporation. And the effects of time, downstream pressure, temparature, and feed concentration on flux and separation coefficient were studied.
