摘　　要：针对目前电厂水中铜离子浓度测量方法操作繁琐的问题,提出了一种快速检测方法,并基于各颜色特征值的变化规律和朗伯-比尔定律建立了硫酸铜溶液浓度、颜色特征值和光程长的计算模型。实验结果表明,该方法及模型可以准确地计算铜离子溶液浓度,而且方法简洁,造价成本低,精度高,实用性强。Aiming at the tedious operation of the existing determination of copper ion concentration, this paper pro- poses a rapid method and establishes the calculation model of concentration, color eigenvalue and pathlength of copper sulfate solution based on the change law of color eigenvalue and lambert - beer ＇s law. Experiment result shows that this method and model, which are simple, low in cost, high in accuracy and practical, are able to accu- rately calculate concentration of copper ion solution.
