摘　　要：在我国环境保护中,水资源保护是极为重要的内容。石油类是我国对水质状况、水污染控制进行评价的重要指标之一,以往分析法中所选取的萃取剂四氯化碳对臭氧层具有破坏作用,因而被禁用,其后产生了新的水质石油类测定法。基于此,本文对新实施的《水质石油类的测定紫外分光光度法(试行)》(HJ 970—2018)方法进行验证。结果显示,试验结果精密度和精准度均符合要求。可见,紫外分光光度法测定水中石油类具有可行性。In China’s environmental protection,water resources protection is extremely important.Petroleum is one of the important indicators for the evaluation of water quality and water pollution control in China,the extraction agent carbon tetrachloride selected in the previous analysis methods has a destructive effect on the ozone layer and is therefore banned,since then a new water quality petroleum method has been developed.Based on this,this article validates the newly implemented method of“Determination of Water Quality and Petroleum by Ultraviolet Spectrophotometry(Trial)”(HJ 970—2018).The results show that the precision and precision of the test results meet the requirements.It can be seen that ultraviolet spectrophotometric determination of petroleum in water is feasible.
