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.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 (NH_4)_2SO_4 and complexing agents were investigated.
