The effects of concentration of mineralized solution (CaCl2?and Na2CO3 solutions) and alternate impregnation times on PVDF@C-TA@CaCO3 membrane were investigated by using water contact angle and pure water flux as evaluation indexes. With the increase of the concentration of mineralized solution and the number of alternate impregnation, the water contact angle of PVDF@C-TA@CaCO3 membrane decreased gradually, and the pure water flux increased first and then decreased. When the concentration of mineralized solution was 0.15 mol/L and alternate impregnation for 10 times, the pure water flux of PVDF@C-TA@CaCO3 membrane reached the maximum of 5 750 L/(m2 h), and the water contact angle decreased to 10 . The retention rates of PVDF@C-TA@CaCO3 membrane to vegetable oil, cyclohexane and petroleum ether emulsion were 90.5%, 93.3% and 91.5%, respectively, and the flux recovery rates were 88.5%, 94.4% and 95.5%, respectively, showing good separation performance of oil-water mixture.更新日期/Last Update: 2022-08-01中国给水排水杂志社官方网所有资料均源在网上的同享资本和期刊同享，请特殊留意勿做其他不法用处 若有加害您的版权或其他有损您好处的行动，请联系指出，本网会当即进行更正或删除有关内容论文颁发投稿邮箱：cnwater@vip.163.comCopyRight (C)2016 中国给水排水杂志社官方网 版权所有 津ICP备20004590号[1]杨胜,孟晓荣,陈嘉智,等.超亲水PVDF@C-TA@CaCO3膜制备和油水份离机能[J].中国给水排水,2022,38(15):14-20.
