温度的变化会影响紫外可见光谱中的吸光度，因此在使用紫外可见光谱监测COD时，应消除温度对光谱的影响。本文将通过实验对COD标准溶液在不同温度下的光谱数据进行测量，然后利用线性回归对数据进行拟合，得到温度与吸光度的具体关系，最后为COD光谱监测建模优化提供一种方法。
Changes of temperature affect absorbance in the UV-Vis spectrum, thus when using UV-Vis spectroscopy to monitor COD, we should eliminate the effect of temperature on the spectrum. In this paper, the spectral data of COD standard solution will be measured at different temperatures through experiments, then use linear regression to fit the data and obtain the specific relationship between temperature and absorbance, finally to provide a method for spectroscopic monitoring of COD modeling optimization.
