主 题:emulsion liquid membrane liquid membrane separation industrial waste-water amino-J acid
摘 要:The emulsion liquid membrane technique was used to extract amino-J acid from industrial dye waste-water.The effects of stirring speed,ratio of the emulsion to water(Rew),ratio of the oil to internal phase(Roi)and membrane phase components on the extraction rate were investigated and optimized.The results showed that the extraction rate of amino-J acid approached 97% when the stirring speed was 300 r/min,Rew 1:6,Roi 1:1,trioctylamine(TOA)3 mL/100 mL kerosene,and methyl?didecyle?alcohol?acrylate(LMA-2)3 g/100 mL kerosene,respectively.The extraction rate had not changed with the oil phase reused for times.
