双环己酮草酰二腙与铜离子在pH=9左右的氯化铵-氨水组成的缓冲溶液中形成稳定的蓝色络合物．测定了该络合物的吸收曲线，确定了最大吸收波长λmax=603．7nm．在此波长下测得铜离子标准溶液的吸光度，所得数据以origin 6．0软件处理分析，得到标准曲线。其线性回归方程为：A=1．0×10^-3＋0．01268x，相关系数γ=0．9983，P〈0，000l（n=4），铜离子的含量在0．10～20．00mg／L之间时，吸光度与铜离子的浓度呈线性关系．该分析法可用于工矿企业含铜废水处理站的日常监测．其准确度、重现性、误差均能符合国家标准水质分析方法规定的范围．

Under the buffer solution of ammonia chloride and ammonia（pH ≈ 9）, bicyclohexone oxalyldidrazone （BCO） and copper ion form the stable blue complex. The absorbance spectra of the complex were measured to determine the maximum absorbance at 603.7 nm. At this wavelength, the standard solution of copper ion was measured to obtain their absorbance and give the standard curve of the complex. The measured results were calculated and pro- cessed by Origin 6.0 programs to get the linear regression equation A=1.0×10^=-3＋0.01268x and the correlation coefficient γ=0.9983. The standard curve shows that the absorbance correlates evident linearly to the concentration of the complex under the concentration of copper ion among 0.10-20.00mg.L^-1. This analyticai method could be used in routine test for the copper wastewater treatment station of the relevant plants. The precision,repeatability and error could comply with the State Standard for water analysis.
