摘　　要：本文提出用SNAZO测定微量铜的分光光度新方法.在非离子表面活性剂TritonX-100存在下,于pH5.6的溶液中,该试剂与铜生成红色配合物,其最大吸收波长为500nm,表观摩尔吸光系数是4.61×10~4,配合物组成为1∶3,铜含量在0-1μg·ml^(-1)范围内服从比尔定律.A method for the spectrophotometric determination of micro-amouts of Copper with SNAZO has been developed. In the presence of non-ionic surfactant(tritonX-100) and pH5. 6solution,Copper reacts with SNAZO to form a red coordination compound. The maximum absorption of the coordination compound is at 500nm and the molar absorptivity ,4. 61×10~4. The molar ration of Cu to SNAZO is 1∶3. Beer's Law is obeyed for copper Concentration range of 0 to 1 μg per ml.
