Treatment of wastewater containing hexavalent chromium is the issue in this research. Supported liquid membrane with in situ electrochemical reaction in stripping section helps to reduce hexavalent chromium to trivalent chromium by forming chromium‐iron complex. Iron plate acts as anode in stripping section. The chromium‐iron complex is an useful value added product that can be used for various purposes such as catalyst in water‐gas shift reaction. Aliquat 336 has been used as carrier for transport of hexavalent chromium. Various physico‐chemical parameters have been optimised to detect the condition of maximum transport and precipitation of chromium‐iron complex in stripping phase. The important physico‐chemical parameters such as strip phase concentration, strip phase pH and concentration of carrier (% v/v) in Liquid Membrane have been selected through response surface methodology to obtain optimum performance for %precipitation of chromium.
