| Abstract: | A bulk liquid membrane consisted of 1.8×10−4 M Janus Green in chloroform that placed between an aqueous source phase containing 0.5 M sodium thiocyanate at pH 7 and an aqueous receiving phase with 0.1 5 M histidine at pH 7 results in an uphill transport of copper from the source phase to the receiving phase. The amount of copper transport through the liquid membrane after 180 min was 97.0±1.7%. The presence of other metals such as Cd2+, Zn2+, Hg2+, Mg2+, Ag1+, Ni2+, Pb2+, Fe3+, K1+, Co2+ doesn't change the efficiency of copper transport. |
