摘要
以表面活性剂二 (2 -乙基己基 )磷酸铵作为反胶束 ,测定其浓度对萃取精氨酸的影响 ,确定最适宜的表面活性剂浓度 .测定水相中 Na Cl浓度对反胶束吸水率和萃取精氨酸的影响 .结果表明 ,以二 (2 -乙基己基 )磷酸铵为表面活性剂所形成的反胶束具有较其它反胶束更强的萃取能力 ,具有良好的吸水性能 .适合于从高盐浓度 (4.5mol·L-1 )的水溶液中 ,萃取出氨基酸 .
The reverse micelle with di(2 ethylhexyl)ammonium phosphate(DEHAP)as surfactant is applicable for extracting amino acid from water solution of NaCl in high concentration.This conclusion is based on the following determinations and investigation:the effect of concentration of DEHAP on arginine extraction,and the optimum concentration of surfactant;the effect of concentration of NaCl in water phase on water absorption rate and arginine extraction. As shown by the results, the reverse micelle with DEHAP as surfactant is able to extract arginine from solution of Nacl in a concentration as high as 4.5 mol·L -1 .It has a stronger capacity of arginine extraction and a higher water absorption rate as compared with those of other ones.
