摘　　要：本文从矿山实际出发,试用碘量法代替原子吸收法测定细菌冶炼酸沥滤液中的铜,建立起不用高档仪器、快速、准确地测定该类样品中铜的方法.实验结果表明,该法稳定性好,适用范围广(浸出液中铜含量在0.2—67g/1均可测定),精密度(RSD)为1.05%(n=10),回收率均达99.82%.In accordance with practical conditions in mining areas, the iodometric titration method has been presented instead of the AAS method for the determination of total copper content in bacteriometallurgical acid leach liquors. It is rapid, accurate and no need of atom absorption spectrometer. It can be applied to a Copper content of 0.2-67g/1. The method gives a -RSD 1.05% ( n = 10) and 99.82% recovery.
