摘要
研究了铜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铜的新方法 ,找到了最佳试验条件。该法线性范围为 0～ 0 0 0 8μg/mL ,检出限为 0 3 9× 1 0 - 3μg/mL ,应用于食品中铜的测定 。
The fading reaction of inhibitory KIO 4 oxidizing bordeaux-red with copper has been studied and a determination method of trace copper by inhibitory kinetic spectrophotometry has been established.The linear range is 0～0.008 μg/mL。The method has been used as a convenient way for the determination of copper in food with satisfactory results.
