以三正辛胺为载体的微乳液分离钼(Ⅵ)的研究
Separation Study of Molybdenum through Microemulsion with Trioctylamine Mobile Carrier
【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.
【Abstract】 In this paper, the behavior and mechanism of separation of Mo7O6-24 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).
