Abstract: In this paper, the application of infrared spectrophotometry to the determination of petroleum and animal and plant oils in water in the monitoring of ecological environment protection is briefly discussed. Oil in water body is one of the routine monitoring projects, which provides a detailed and reliable scientific basis for ecological and environmental supervision and control. Strengthening technical innovation and development, and carrying out efficient and correct analysis and monitoring are essential links for preventing and controlling oil pollution and purifying water ecological environment. Based on advanced equipment and scientific methods for environmental monitoring, from the practical application, the purity of tetrachloroethylene and other interference in the operation, it is difficult to ensure the accuracy and precision of the determination, so it is necessary to strengthen technical exploration.

Key Words: Infrared spectrophotometry; Oil in water; Tetrachloroethylene; Detection application

现阶段,随着我国工业化进程的加快以及经济水平的不断提高,工业废水及生活污水排放量加大,导致水污染问题越来越严重,需要我们提高对环境综合治理的重视,其中环境生态监测工作就是环境综合治理中尤为重要的一部分内容,它是环境保护的一项基础性工作,是环境决策的重要依据。在世界环保组织公布的48种危险污染物中,油类占第8位,因此加强油类监测技术为后续生态环境保护工作的展开提供科学的数据信息成为研究重点。

1  水体中油类污染物的危害

油类是水体环境中的主要污染物之一,在水体监测中也是一项重要的监测项目。油类物质难溶于水,能够溶于四氯化碳、正己烷、四氯乙烯等有机溶剂[1]。油类污染物存在于地表水、海水、渔业水、农田……
