    Abstract

    ABSTRACT Dewi Sukmawati, 2007, THE EXTRACTION OF Cu2+ USING LIQUID MEMBRANE TRANSPORT METHOD BY FORMATION OF Cu-OXINAT COMPLEX. Thesis. Departement of Chemistry. Mathematic and Science Faculty. Sebelas Maret University. The extraction of Cu2+ using liquid membrane transport method by formation of Cu-oxinat had been done. The research was determined optimum conditions of Cu2+ extraction with oxine, that were pH of source phase, extraction time and to determine the efficiency extraction in transport single metal and transport with many metals. The determination of pH was carried out in batch method with extraction time 10 minutes, equilibrium time 10 minutes and oxine concentration 1,25 x 10-2 M with variation pH were 2, 3, 4, 5, 6. The determination of extraction time was carried out using liquid membrane transport method with variation extraction time were 1, 2, 3, 4, 5, 6 and 7 hours. Acid which was used in receiving phase was H2SO4 0,05 M. Metals which were used to determine the effectivity of oxine were Fe 3+ , Cr 3+ , Cd2+ , Pb2+ , Zn2+ and Ni 2+ . The analysis metals in water phase were determined by Atomic Absorbtion Spectroscopy (AAS). The result showed that extraction of Cu2+ with oxine under optimum condition were extraction time 10 minutes, equilibrium time 10 minutes (batch method), pH solution was 3, extraction time 4 hours (liquid membrane transport method). The efficiency extraction of Cu2+ using liquid membrane transport method in transport single metal in receiving phase under optimum condition was 45,18% and for Fe 3+ , Cr 3+ , Cd2+ , Pb2+ , Zn2+ , Ni 2+ were 0% respectively, in the other hand the efficiency extraction of Cu2+ in transport with many metals in receiving phase was 35,95% and for Fe 3+ , Cr 3+ , Cd2+ , Pb2+ , Zn2+ , Ni 2+ were 0% respectively.
