The separation of mercury in a microemulsion composed of OP-10/iso-pentanol/cyclohexane/NaOH was studied.When 0.03 mol/L triisooctylamine (TIOA) in the membrane phase,0.03 mol/L NaOH in the stripping phase,and 0.05 mol/L HCl and 0.10 mol/L KBr in the feed phase were used,the percent extraction of Hg(Ⅱ) was more than 98%.Under the chosen conditions,Hg(Ⅱ) could be completely separated from Fe(Ⅲ),Co(Ⅱ),Ni(Ⅱ),Zn(Ⅱ),Mn(Ⅱ),Cd(Ⅱ) and Pb(Ⅱ).
