摘　　要：采用双环己酮草酰二腙光度法，建立小体积目视比色测定矿石中铜的方法，检测范围为0．01％～5％，方法用国家一级标准物质进行验证，测定值与标准值相符。该法灵敏度高，选择性好，无需分析仪器，适用于铜的野外快速测定。A small-capacitiy method for visual colorimetric determination of copper in the ore by bicyclic cyclohexanone oxalyl dihydrazone was established in this paper. The method was used to determine the copper in the rang of 0.01% to 5%. The results were in good agreement with the certified values of the national standard materials of rocks. The method has been successfully used in practice for field rapid analysis of copper with high sensitivity and good selectivity without instruments.
