红外与紫外测试矿物油的方法比较

The comparison of infrared spectrophotometry and ultraviolet pectrophotomery in determining the concentration of petroleum

通过对不同沸程的标准矿物油油品分别进行红外分光光度法和紫外分光光度法测试的比较实验,证明红外、紫外两种方法的适用范围存在差异,对一般未知油品,以红外分光光度法所测结果更接近水体中油品的实际含量．

In the paper an experiment was designed to check which one is better in determining the concentration of petroleum： infrared spectrophotometry or ultraviolet pectrophotomery. The result shows infrared spectrophotometry is more accurate in doing this work.
