ABSTRACT: Iodine transport
throught bulk liquid membrane technique consist of 10 mL I2/KI 4x10-3 N solution
as donor phase, 20 mL Na2S2O3 0.02 N solution as reagent striping in acceptor
phase, and 30 mL chloroform as membrane phase. Technical operation use magnetic
stirring at 100 rpm. Concentration of iodine in donor phase and acceptor phase
determined by Spectrophotometer UV-Vis λ max at 567 nm. The results concluded
that the optimumconditions of iodine transport 4 x 10-3 N with pH 7 in donor
phase, comparison I2:KI in donorphase (1:5), and a long stirring is 120
minutes. The bulk liquid membrane technique with Na2S2O3 as reagent striping in
acceptor phase is potential for iodine transport from donor phaseto acceptor
phase with 86.71 % of iodine transport. Fluxs values (transport rate) generated
by using chloroform membrane of 1.8872 x 10-7 L/cm2.menit-1 at a maximum
transport time of 120 minutes.
