【摘要】 对胶团强化超滤法（MEUF）处理氯乙烯生产废水中的有机污染物1,2-二氯乙烷（DCE）进行了研究.讨论了3种阳离子表面活性剂（SAA）十六烷基三甲基氯化铵（CTACl）、十六烷基三甲基溴化铵（CTABr）、溴代十四烷基吡啶（CPBr）对1,2-二氯乙烷（DCE）的增溶作用.应用顶空气相色谱法分别测定了DCE在3种SAA中的最大增溶量C_max,从而计算出增溶系数K_i.比较发现,CTACl对DCE的增溶能力优于其他两种.应用CTACl对DCE增溶并形成胶团后,选用聚砜、聚丙烯腈膜进行超滤实验,测定并分析了不同截留分子量、不同材料的超滤膜对胶团的分离性能.更多还原

【Abstract】 Treatment of organic contamination- 1,2 - dichloroethane in chloroethylene wastewater by micellar -enhanced ultrafiltration was studied.The solubilization of three cationic surfactants（CTACl、CTABr、CPBr） to 1,2-dichloroethane（DCE） was discussed.DCE’s maximal solubilizing amount(C_max) in three surfactants were mensurated by using headspace gas chromatograph and its solubilization coefficient（K_i） were reckoned. By comparing,that CTACl’s solubilization to DCE was better than the other two surfactants was concluded.After the solubilization of CTAC1 to DCE,ultrafiltration experiments of polysulfone membrane and polyacrylonitrile membrane were discussed,and the separate performances of different MWCO and different material to micellar were mensurated and analysed.更多还原
