| 摘 要： | 提出伏安双点滴定法。研究了用ＡｇＮＯ３标准溶液作滴定剂的实验条件。本法用玻碳电极作工作电极，在ＫＮＯ３及ＨＮＯ３等溶液中，不需要除去溶液中的氧。用此法测定ＫＢｒ标准溶液，其结果与电位滴定法相符，具有简便、快速和准确等优点。

| Abstract: | A method of double-point voltammetric titration with AgNO3 as titrant is presented in which a glass carbon electrode is used as a working electrode. This method exhibits good accuracy and is simple and easy to use. It has been used successfully for determining KBr without removing oxygen from the solutions studied. The results obtained are consistent with those by potentiometric titration. Sodium chloride and ephedrine chloride in drug are determined by double-point voltammetric titration with silver nitrate as titrant. Results are satisfactory for several kinds of samples. |
