应用电析吸附法,将混合氨基酸溶解于5％NA2SO4溶液体系中,调节PH＝3.0,将其置于膜面积为400CM2的电析池中,接通电源,施加3A/电流强度形成的电场,经24H电析,使酸性氨基酸向阳极运动,碱性氨基酸向阴极运动,中性氨基酸仍停留在淡化池中.碱性氨基酸和酸性氨基酸的迁移率均达到90％以上.然后将碱性氨基酸通过活性炭处理,有95％以上的精氨酸被吸附,而赖氨酸不被吸附,达到分离与纯化之目的.“,”Mixed Amino solution is soluted in Na 2SO 4 system in electrodialysis pool with 400 cm 2 are of membranel in the method of electrodialysis absorption. pH=3.0, connect power, power supply(3A/m 2) turn into electric field after two hours electrodialysis so that acids capacity amino move to cathode, basis capacity amino move to amode, rest still stayed in solution. 90%of basic and acids capacity amino can be moved, and then basic capacity amino through active charcoal, 95%of Arginine can be absorpted, bu...
