摘　　要：介绍了一种光亮镀镍液中硼酸和氯化镍的测定方法。采用 732型阳离子交换树脂分离镍及其它阳离子后 ,分别用氢氧化钠和硝酸银滴定硼酸和氯离子。分析结果表明 ,本方法简便快速、准确度高。A method for continuous titration of boric acid and nickel chloride in bright nickel plating bath was presented. Type 732 cation exchange resin was added in nickel bath to separate nickel ions and other cations, boric acid and chloride ions were then separately titrated by sodium hydroxide and silver nitrate. The results show that this method is simple, rapid and accurate.
