摘要
河流、湖泊、码头、水库中矿物油污染问题越来越严重,矿物油污染监测问题已经为环保部门高度重视,各种检测水中油的仪器和方法也不断发展起来。本文分析了水中矿物油检测技术的基本工作原理和仪器方法,包括:红外光谱法、紫外分光光度法、光反射法和紫外荧光法,比较了不同方法在测定矿物油时各自的优点和缺陷。其中,紫外荧光检测由于灵敏度高,速度快,便携,可用于实时在线连续检测,且检测结果具备很高的可靠性,成为未来水中油检测优先考虑的方法。
The question of oil pollution in water as rivers, lakes, ports and reservoirs, becomes more and more strictly. It has been attached great importance to environmental protection departments. And various of equipments and methods have been developed. In this paper, the principles and instruments of related petrolatum measurement for oil in water are analyzed, including infrared spectrometry, uhraviolet spectrometry, optical reflection method and ultraviolet fluorescence spectrometry, comparing their advantages and differences. In the all, the UV fluorescent spectrometry is likely to be the most priority technology because it is sensitive, rapid, portable, reliable and suitable for continuous online water detection.
