摘　　要：对比研究了红外法和紫外法测定水中石油类的新旧标准方法,包括3种红外法测定标准和5种紫外法测定标准。对历次标准修订的背景、过程、变化等进行解读,对两种标准测定方法的测定原理、萃取剂、测定过程和结果、校准方法、检出限、精密度和准确度等进行对比分析,并提出相关完善建议,为相关水生态环境监测和服务地方河湖长制工作提供参考。The author compared the new and old standards for the determination of petroleum in water by infrared spectrophotometry and ultraviolet spectrophotometry, including three infrared spectrophotometric and five ultraviolet spectrophotometric standards. The background, process and changes of previous standard revisions were explained. The author also compared and analyzed these two determination methods in respects of the detection principle, extractant, determination procedures and results, calibration method, detection limits, precision and accuracy.Relevant improvement suggestions were proposed to provide reference for the monitoring of water ecological environment and the work of local river and lake chief system.
