| Abstract: | The membrane composition and the effect of several important operating perameters on the extraction of the lysine,as well as the swelling rate,the stability of the liquid emulsion membrane(LEM) and the efficiency of separation,were systematically studied by LEM method.The membrane used to extract lysine was composed of 7%(mass fraction) D2EHPA as carrier,5%(mass fraction) Span-80 as the emulsifier and a mixture of 50%(volume fraction) paraffin and 50%(volume fraction) kerosene as the solvent.A solution with a concentration of 0.5 mol/L HCl was used as the internal phase.The treating ratio was 3.75.It has been demonstrated that 72.6% of lysine can be extracted from the external phase. |
