| Abstract: | This paper includes the following experiments:feed type comparision (NaCl-type or (NH4)2SO4-type),NaAc addition amount,with or without paraffin in membrane phase,membrane recovery and reuse.A suitable liquid membrane system(N205-P507-kerosene-HCl) is obtained for concentrating RE from (NH4)2SO4 type leachate.The concentration of RE in rich liquid from membrane can reach 102 g.L-1 with extraction efficiency of 93%. |
