摘　　要：建立了微波辅助消解-微型自动光度滴定法测量铜的方法。用4个有证标准物质验证方法的准确度,回收率为99.8%～99.9%。与经典方法相比,该法更加快速、准确,适合于铜矿石中Cu的测定。A method for the determination of copper by automatic photometric titration was developed, with the use of a microwave assisted digestion method. Four certified reference materials （CRMs） were tested and the accuracy of the proposed method was validated. The recoveries were 99. 82% -99. 97%. The proposed method is less timeconsuming and more accurate than the classic methods. It is suitable for the determination of copper in copper ores.
