Ni-mSA/CS bipolar membrane was prepared from sodium alginate and chitosan and used as a separator in the electrolysis cell to produce thioglycolic acid(TGA).The FTIR,mechanical properties,moisture content and ion exchange capacity of membranes were investigated.The nickel net was settled down on the surface of mSA membrane to realize zero polar distance electrolysis in the cathode room.The experimental results showed that thioglycolic acid was prepared effectively by electro-reduction of dithioglycollic acid blended with thioglycolic acid in the cathode room and 25% H2SO4 as the anode electrolyte.The current efficiency was up to 66.7% at room temperature when current density was 10 mA·cm-2.
