Abstract

Zn(II) transport from the source phase into the feed phase had been researched by using ditizone as carrier through bulk liquid membrane. Ion transport are started by adding 6 ml source phase that consist of Zn(II), 12 ml receiver phase that consist of Na2EDTA and 20 ml membrane phase that consist of ditizone as carrier. The experiment operation technic was assisted by magnetic stirrer mixing at 340 rpm speed within 15 minutes equilibrium time. The measurement was done to both of source phase and receiver phase by using atomic absorption specktrophotometer at max 213.9 nm until Zn(II) was transported to receiver phase and residu in source phase was gathered. The research result that optimum condition to transport 3,06 x 10-4 M Zn(II) was at pH 8,5 of source phase, 1,75 x 10-5 M ditizone concentrate at membrane phase, 0,06 M EDTA concentrate at pH 6 in receiver phase and 3 hours transport time with Zn(II) percentage which was transported to receiver phase 93% and residu in source phase do not detect. Keywords : transport Zn(II), bulk liquid membrane, dithizone
