Abstract
The permeation of Cr(VI) from acidic media, through a dispersion supported liquid membrane (DSLM), impregnated with tri-n-octylamine (N235) in diluent has been investigated in flat-sheet operational mode. Effects of operational factors including stirring speed, initial Cr(VI) concentration, N235 concentration, NaOH concentration, and the volume ratio of liquid membrane and strip liquor in dispersion phase on Cr(VI) transport have been studied. The evaluation of Cr(VI) separation from hydrochloric acidic media was carried out. Under the optimal condition, the migration rate of 0.01 g/L Cr(VI) was observed as 94%.
