二.溶出伏安法测定阴离子: 用化学分析,电位滴定、安培滴定、经典极谱分析的方法测定阴离子,最高灵敏度不超过1×10~(-4)—1×10~(-5)M,为了提高测定阴离子方法的灵敏度,较有效的方法是用阴极溶出伏安法,因为它先在金属固体电极上以难溶化合物形式富集。这个方法的原理和定最测定的规律及应用它来进行具体样品分析的可能性在前面已经阐明。现已可用这个方法测定氯离子, Determination of Anions by Stripping Voltammetry: The anions are determined by chemical analysis, potentiometric titration, amperometric titration and classical polarographic analysis. The highest sensitivity does not exceed 1 × 10 -4 -1 × 10 -5 M , In order to improve the sensitivity of the anion method, a more effective method is to use cathodic stripping voltammetry because it is first enriched in the form of a sparingly soluble compound on a metal solid electrode. The rationale for this method and the most determined rule and the possibility of using it to perform a specific sample analysis have been elucidated earlier. Now available to measure chloride ion,
