红外差谱法检测水中的矿物油

Differential Method for Detecting Mineral Oil in Water by Infrared Spectroscopy

随着环境条件的恶化,水体污染日益增多。而水体污染物种类繁多,因此对于污染物的定性分析有利于污染的控制。矿物油作为水体污染物之一,由于其密度低于水,在污染物含量较少的情况下采样人员很难将矿物油从水体中分开导致了矿物油与水的混合物产生,从而很难定性分析。本文主要探讨了红外差谱法检测水中的矿物油成分。

With the deterioration of environment,the pollution of rivers and lakes has been increasing.There are many kinds of pollutants that may be discovered in water,thus to quantitatively analyze the pollutant belongs to which kind may help to control the pollution.As one of the major pollutants,the mineral oil is difficult to separate from water because it is lighter than water and usually doesn’t have a large amount in water.Thus,the mixture of water and mineral oil is often sampled due to the reason above,which may lead to the difficulty in further qualitative analysis.So,how to quantitatively analyze the mineral oil in the mixture becomes a new challenge.In this article,the differential method of infrared spectroscopy was introduced to solve this problem.
