摘　　要：采用紫外光谱法测定Cu^(2+)和Bi^(3+)的浓度,选择在最大吸收波长280和320nm处,分析Cu^(2+)和Bi^(3+)的浓度与紫外光谱的吸光度数值之间的相关性。在一定浓度的4,6-二正丁氧基-1,3-二磺酰二甲基胺基苯的溶液中加入5个浓度的Cu^(2+),在化合物-Cu^(2+)的体系中加入7个浓度的Bi^(3+),测定紫外光谱,绘制标准曲线。结果表明,Cu^(2+)和Bi^(3+)的浓度与吸光度数值都呈显著相关,标准工作曲线y=0.0564x-0.0274和y=0.1005x+0.038其相关系数达到0.9892和0.9968,说明用紫外光谱法检测Cu^(2+)和Bi^(3+)浓度简单、快速且测定结果准确可靠。In the paper, concentration of Cu^（2＋）and Bi^（3＋）was Detected by UV spectroscopy. Cu^（2＋）and Bi^（3＋）solution ofdifferent concentration were added into fixed consistent 4,6- Bis- butyloxy- benzene- 1, 3- Di（N, N- dimethylsulfonamides）, ultraviolet spectrum were checked out, the relevance between Abs in UV spectra and concentration ofCu^（2＋）and Bi^（3＋）was analysed. The results show that the maximum absorption wavelength was 280 and 320 nm by UV-Spectrum and the correspondence coefficient was 0.9892 and 0.9968 with equation y = 0.0564x- 0.0274 and y=0.1005x＋0.038. The method in measuring concentration of Cu^（2＋）and Bi^（3＋）by ultraviolet spectrum is simple, rapid, accurate, feasibleand reliable.
