摘  要:The extraction behavior of Fe(Ⅲ), Cu(Ⅱ), Co(Ⅱ), Mn(Ⅱ), Pb(Ⅱ), Ni(Ⅱ) and Hg(Ⅱ) by microemulsion Triton X-100 (α-(4-(1,1,3,3-tetramethy(butyl)phenyl)-ω-hydroxy)poly(oxy-1,2-ethanediyl) in the presence of (NH4)2SO4 and complexing agents were investigated. The results indicated that the complexes of Fe(Ⅲ) with aluminon were almost completely extracted in HAc-NaAc buffered microemulsion while Cu(Ⅱ), Co(Ⅱ), Cd(Ⅱ), Mn(Ⅱ) and Hg(Ⅱ) were not. Quantitative separation of Fe(Ⅲ), Co(Ⅱ) and Mn(Ⅱ) were realized. The extraction mechanism by O/W microemulsion has been discussed.
