The reactor was constructed with a lead plate as cathode, and platinum as anode. The catholyte was cystine in HCL solution, and the anolyte was 0¡P1 n H2SO4 solution. The catholyte and anolyte were separated by a cation exchange membrane. When the electrode distance was 0¡P65 cm, catholyte concentration was 0¡P4 m cystine, the process was operated at 30¢XC, 200 ml/min of flow rate and 20 mA/cm2 of current density, a current efficiency of 91¡P5% could be achieved. After electrochemical reaction was completed, the cysteine crystal was obtained by further concentration and crystallization. The overall recovery of cysteine crystal reached 91%. ? 1991. |
