摘 要: 研究了以三正辛胺(TOA)为载体,由OP-10、异戊醇、环己烷和NaOH水溶液组成的微乳液分离钼(Ⅵ)的行为及机理.当膜相中三正辛胺浓度为0.03 mol/L,内相NaOH的浓度为0.03 mol/L,外相HCl的浓度为0.01 mol/L,可使钼(Ⅵ)的萃取率达98%以上.在该条件下,可使钼(Ⅵ)与Fe(Ⅲ)、Co(Ⅱ)、Ni(Ⅱ)、Zn(Ⅱ)、Mn(Ⅱ)、Cd(Ⅱ)、Cu(Ⅱ)、Pb(Ⅱ)完全分离. In this paper, the behavior and mechanism of separation of Mo7O24^6- through microemulsion composed of OP- 10/iso-pentanol/cyclohexane/NaOH were studied. When 0.03 mol/L trioctylamine (TOA) in the membrane phase, 0. 03 mol/L NaOH in the stripping phase, 0.01 mol/L HCl in the feed phase, the percent extraction of Mo ( Ⅵ ) was 〉98%. Under the chosen conditions, Mo ( Ⅵ ) could be completely separated from Fe ( Ⅲ ), Co ( Ⅱ ), Ni ( Ⅱ ), Zn( Ⅱ ), Mn ( Ⅱ ) ,Cu( Ⅱ ) and Pb( Ⅱ ).
