摘　　要：针对传统化学需氧量(COD)检测方法较为繁琐的问题,文中提出了导数光谱-化学计量学方法来快速测定制浆废水COD.该方法是通过化学计量学软件,根据一组已知COD制浆废水的多波长导数光谱和所对应的COD之间的数学关系,建立校正模型;然后将未知水样的导数光谱信息输入校正模型中即可预测其COD值.该方法无需使用化学试剂,快速、准确、便捷,为制浆废水COD检测提供了一个新方法.In order to simplify the determination of chemical oxygen demand （COD） of pulping effluent using the conventional methods, a high-speed derivative spectrophotometry-chemometrics method is proposed. In this method, based on the mathematical relationship between the multi-wavelength derivative spectral signals and the known COD values of a set of pulping effluent samples, a calibration model is established using a chemometrics software. With this model, the COD value of a certain pulping effluent can be easily predicted according to the multi-wavelength derivative spectral signals. The proposed method provides a new and convenient approach to the high-accuracy COD determination of pulping effluent without using any chemical reagents.
