영문 초록

Hollow fiber module contactor can be designed to provide a very high surface area per unit volume, which makes them very effective in comparison to conventional extraction equipment. Since the phases are separated by the membranes, the loading, flooding, and channeling constraints of conventional equipment are avoided. The optimum conditions for the change of H^+ concentration in heavy metal(Cu(II), Ni(II), Pb(II), Zn(II), Cd(II)) solution, the change of flow rate inside-outside hollow fiber membrane and the removal of heavy metal by the sort of extractant(Lix84-n-heptane, TOA-n-heptane, D2EHPA-n-heptane) were examined through perstraction of aqueous phase heavy metal from the hollow fiber module by organic extractant. Lix84 showed the best efficiency to Cu(II) extraction among a few kind of used extractant
