| 摘 要： | 研究提出了一个快速测定铂（Ⅳ）的零电流示波电位滴定法。以氯化十六烷基吡啶（ＣＰＣ）为滴定剂，用铂电极和银电极为指示电极，利用阴极射线示波器荧光屏上荧光点的突然位移来指示ＣＰＣ滴定Ｐｔ（Ⅳ）的终点，具有灵敏、准确、快速等特点，用此法测定陶瓷铂金水中的铂，结果良好。

| Abstract: | n this paper, a simple and rapid method of zero-current oscillopotentiometric titration of platinum is introduced. Platinum electrode and silver electrode areusaed as indicator electordes. Cetylpyridinium chloride (CPC) solution is used as titrant.The end point of titration of Pt(IV) by CPC is indicated by the sudden movement of a fluorescent spot on the'fluorescent screen of a cathode-ray oscillograph. The new method hasthe characteristics of sensitivity, precise and quick. With the help of the method, the results of determining the amount of Pt(IV) in Pt-solution for glazed ceramic agree quitewell with the reference values. |
