Abstract: Kinetics of Cr(III) ions transport through a bulk liquid membrane containing dinonylnaphthalenesulfonic acid (DNNSA) as a carrier, flowing over aqueous phases, has been examined. Special attention has been paid to the effect of the membrane’s velocity flow on the chromium concentration decrease in a feed phase. For the description of relationships of chromium(III) concentration in particular phases with the time, a model based on the assumption of consecutive first-order reactions was proposed. Satisfactory compatibility of experiments and model results have been obtained both for the membrane flow velocities below 0.0034 m·s-1 when the interfaces begin to fluctuate slightly and for low initial Cr(III) concentration in the feed phase.
Keywords: Transport kinetics of chromium(III); dinonylnaphthalenesulfonic acid (DNNSA); bulk liquid membrane
