文章探讨了含铜土壤中铜的赋存状态，并对土壤中铜的物相分析方法进行了研究。结果表明：用乙二胺浓度为0.05 mol/L（pH=10）的溶液浸取自由氧化铜，用含有Na2SO3和NH4HF2的H2SO4（0.9 mol/L）溶液浸取结合氧化铜，用含有硫脲（200 g/L）的HCl（1.0 mol/L）溶液浸取次生硫化铜能获得满意的结果。在最佳浸取条件下对含铜土壤中的铜进行物相分析和基准矿物回收试验，结果满意。

To research the occurrence state of copper in the soil containing copper and the phase analysis method of the copper. It was shown that using ethylenediamine 0.05 mol/L(pH=10) to soak out free copper oxidie, the bonded copper oxide was soaked out by H2SO4(0.9 mol/L) solution containing Na2SO3 and NH4HF2 and secondary sulfide copper by HCl(1.0 mol/L) solution containing thiarea. In the optimum condition, the method has been applied to phase analysis of copper in the soil containing copper and standard ores recovery test with satisfactory results.
