摘　　要：用伏安法测定酸性氯化钾镀锌液中的锌。结果表明:在pH值为10的NH_3-NH_4Cl缓冲溶液中采用多次标准加入法测定氯化钾镀锌液中的锌,镀液无需做任何处理便可直接稀释测定。该方法能满足酸性镀锌工业中批量样品快速分析的需要,准确度和精密度均能满足生产要求。A method for the determination of zinc solution using voltammetry was introduced. Results in acidic potassium chloride zinc plating show that the determination of zinc in potassium chloride zinc plating solution by multiple standard addition method in NHs NH4Cl buffer solution （pH 10）, the plating solution can be directly determined after diluted without any treatment. This method can meet the need of rapid analysis of batch samples in acidic zinc plating industry, and its accuracy and precision can meet the production requirements.
