摘要
研究了银阻抑高碘酸钾氧化玫瑰桃红R的褪色反应,建立了阻抑动力学光度法测定痕量银的新方法.找到了最佳试验条件,该方法线性范围为0～2.0 μg/mL,应用于水中银的测定,结果满意.
The fading reaction of inhibitory KIO4 oxidizing Bordeaux - red with silver has been studied and the determination method of trace silver by inhibitory kinetic spectrophotometry has been established. The linear range is 0-2.0μg/mL. The method has been used as a convenient way for the determination of silver in water with satisfactory results.
