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。
介紹瞭一種光亮鍍鎳液中硼痠和氯化鎳的測定方法。採用732型暘離子交換樹脂分離鎳及其它暘離子後，分彆用氫氧化鈉和硝痠銀滴定硼痠和氯離子。分析結果錶明，本方法簡便快速、準確度高。

A method for continuous titration of boric acid and nickelchloride 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.
