%X Micellar enhanced ultrafiltration(MEUF) is a new method which is based on the surfactant of the unique characteristic of parental molecular structure that can remove heavy metals in the water. The concentrated solution by dealing with the MEUF contains high concentration of heavy metal ions, so it must be need for further processing. The electrolysis method was employed to recovery Cd~(2+) from the concentrated solution of micellar enhanced ultrafiltration(MEUF) .Effects of type of electrode, electrolysis voltage( U) and time( t) .solution pH, surfactant to Cd~(2+) molar ratio (SDS]/Cd~(2+)]) on Cd recovery efficiency were investigated. The study found that the surfactant had some effect of resistance to electrolysis process. The optimum experimental conditions were obtained: stainless steel (anode)-graphite (cathode) , U = 2.8 V, t = 100 min,pH = 4, SDS]/Cd~(2+)] = 5(SDS] =8.5 mmol/L constant) .And the recovery efficiency of Cd~(2+) in the concentrated solution was 50.26%.
