| 摘 要： | 以铜(Ⅱ)为修饰物，铜片为基体，制成铜修饰电极．提出了一个快速测定铜(Ⅱ)的示波电位滴定法．以EDTA为滴定剂，甘汞电极为参比电极，修饰铜电极为指示电极，利用阴极射线示波器荧光点的突然位移指示EDTA滴定铜的终点，具有准确、灵敏、快速等特点，用该法测定含铜(Ⅱ)试样，结果良好．

| Abstract: | Copper modified electrode with Cu~(2+) is employed for the rapid detemi-nation of copper() by oscillo-potentiometric titration. The copper-modified electrode is used as an indicator electrode,while the calomel electrode as a reference electrode.EDTA solution is used as titrant.The end point of coppr by EDTA is indicated by the sudden movement of a fluorescent spot on the screen of the cathode-ray oscillograph.This new method features sensitivity,precision and rapidness.Results of copper() determination are in agreement with the reference values quite well. |
