| Abstract: | This is a continue of the work-- "The concentration of REfrom NaCl--type leachate with emulsive liquid membrane", made byauthor, but for (NH4)2SO4 type feed.It includes the following experiments: feed type comparision (NaCl--type or (NH4)2SO4--type). NaAcaddition amount, with or without paraffin in membrane phase, membranerecovery and reuse. A suitable liquid membrane system (N205-- P507-kerosene--HCl) is obtainel for concentrating RE from (NH.),SO. typeleachate. The concentration of RE in rich liquid from membran ecan reach 102g/L with extraction efficiency of 93q0. |
