摘　　要：基于铜（Ⅱ）对刚果红溶液与紫外光发生光化学反应的催化作用，建立了测定痕量铜的新方法。线性范围０－０２ｕｇ／ｍｌ，相对标准偏差在０．４９％－３．８２％之间，标准加入回收率为９７％－１０３％。用环境土壤标准样品对照分析，结果与标准参考值相符。A new trace analysis method for copper was developed based on the catalysis of copper(Ⅱ)on the*photochemical reaction of Congo Red with UV radiation. The linear range was 0-0.2 ug/ml.RSD were between*0.49%t-3.82% in the standard sample analysis and the recovery were between 97%-103% in the standard addition analysis.*The results in the analysis of standard samples of environmental soil are agreed satisfactorily with the reference values.*
