摘　　要：OCA99是一种锌酸盐镀锌的添加剂,由美国Udylite公司引进的产品,它包括辅助光亮剂OCA991和主光亮剂0CA992。本文通过测定微分电容曲线和极谱曲线研究它们的吸附行为和电化学氧化还原性。根据实验结果,提出控电位微分电容法测定OCA992浓度的方法。OCA99 is an additive in the alkaline zincate bath, from Udylite Co. of USA, included assistant brightener OCA991 and essential brightener OCA992.Their aolsorptive behavior and the electrochemical redox Characteristic were studied by means of differential Capacity measurement and polarograph methods. According to the experimental results, the differential capacity measurement is used to determine the concentration of OCA992.
