摘　　要：研究了铜电解液中高含量铜的光度分析。直接利用水合铜离子的蓝色，双波长扣除试样浑浊干扰；标样以硫酸为介质消除硫酸根干扰；于标样中加入定量的镍，并选择适当的波长克服镍的干扰。实现了贵溪冶炼厂铜电解液中铜（３０～６０ｇ／Ｌ）的自动快速分析，２４０次进样／ｈ。Highly concentrated copper in electrolyte was determined automatically and rapidly by a spectrophotometry based on the color of the hydrated copper ion. The interference of turbidness which is caused by thiourea and bone glue was corrected by dual wavelength measurement. The interference of SO 2- 4 was corrected by adding H 2SO 4 to the standard solution. The hydrated nickel ion interferes in the determination of copper because it is green. NiSO 4 was added to the standard solution in order to eliminate this interference, since the content of nickel in copper electrolyte is relatively constant. The method has been used successfully at Guixi Smeltery. Loading frequency of 240 samples per hour was obtained.
