摘　　要：本文研究了采用W／O型乳化液膜提取柠檬酸过程中影响柠檬酸传质的主要因素。讨论了载体、助溶剂、内相反革试剂等对柠檬酸萃取的影响．实验结果表明：柠檬酸的提取率随载体三烷基胺（C7～10）和内相反萃试剂Na2CO3浓度的增加而增加．膜相中加入正辛醇能显著提高柠檬酸的传质速率。liquid Suthetant membranes (LSMs) were applied to the seperation of citric acid from an aqueous feed soluhon. The effect of variables such as carrier, synergishc diluent stripping agent on citric acid transpont were inveshgated. The experimenta results showed that the extIachon percent of citric acid was increased by an inceeases in concentalon of carier and strippng agent The transport rate of citric acid was also increased by adding 5% octanol to the membrane phese
