摘　　要：实验表明在Ｃｕ（Ⅱ）─邻苯二酚─Ｈ２Ｏ２体系中加入Ｃｌ－和Ａｌ３＋对该体系有一定的活化作用，可进一步提高测定微量铜的灵敏度，通过实验确定了测定微量铜Ｃｕ２＋的最佳条件。可测铜在０．１μｇ以下。The experiment was shown that Cl- and Al3+ had some catulytic actions on Cu (Ⅱ)--H2O2 systems and they would improve the sensitivity of the determing of trace copper.In this peper, the optimal condition for the measurement of trace copper has also been given. The restriction of copper is under 0.1mg.
