摘　　要：利用自制的CuTsPc-SA/CuTAPc-CS双极膜(CuTsPc:四磺酸基铜酞菁;SA:海藻酸钠;CuTAPc:四氨基铜酞菁;CS:壳聚糖)作为电解槽隔膜,成对电解L-胱氨酸合成L-磺基丙氨酸和L-半胱氨酸,提高了电流效率,降低了生产成本。研究表明,电解时电流密度以35mA/cm2为宜,阴极室L-胱氨酸的初始浓度以0.65mol/L为宜。当氢溴酸浓度为3 mol/L时,阳极室电流效率达到最大值,为85.1%。The prepared CuTsPc-SA/CuTAPc-CS bipolar membrane（CuTsPc： copper phthalocyanine tetrasulfonic acid;SA： sodium alginate;CuTAPc： copper tetraaminophthalocyanine;CS： chitosan） was used as a separator in an electrolysis cell for paired electro-generation of L-cysteine in cathode chamber and L-cysteic acid in anode chamber.Paired electro-generation of L-cysteine and L-cysteic acid using bipolar membrane technology improved the current efficiency of electrolysis cell and reduced product cost.The experimental results showed that the optimum current density was 35mA/cm2 and the optimum initial concentration of L-cystine in cathode chamber was 0.65mol/L.When HBr concentration was 3mol/L,the average current efficiency in anode chamber reached the maximum value which was 85.1%.
