Overview on membrane based solvent extraction and pertraction through liquid membranes and their application in recovery of heavy metals from aqueous waste solutions. Recent data shows potential for these processes. Results of experimental study of influence of sulfuric acid concentration in the stripping solution on pertraction rate are presented. Liquid membrane with carrier Aorga P50 was studied. Rate of stripping is much slower than rate of extraction even when using 4M H2SO4. This fact should be reflected in model of mass-transfer presented in the paper. Further study should be directed to search for modifier enhancing stripping rate.
