THE EXTRACTION OF CITRIC ACID BY LIQUID SURFACTAM MEMBRANE
乳化液膜提取浓缩柠檬酸的研究

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
