Kinetics of Chromium(III) Transport Through a Liquid Membrane Containing DNNSA as a Carrier

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