摘要
紫外分光光度(UV)法测定COD技术中,温度是影响的重要因素之一,通过实验测定出标准溶液的紫外吸光度随温度变化的数据,利用多元线性回归的方法对数据进行拟合,得出两者之间的关系,以消除温度的影响。
Temperature is one of the important influential factors in COD measurement with UV spectrophotometry. The data of the UV absorbance of standard solution with the change of temperature were determined experimentally. The relationship between temperature and UV absorbance was obtained by fitting the data with multielement linear regression to eliminate the ifluence of temperature.
