摘要
二氧化硫是主要的大气污染物之一,对呼吸道粘膜和眼睛具有强烈的刺激作用,对机体危害很大。不仅是气象、环境部门常规的监测项目,也是煤、石油石化企业重要的职业病危害因素监测项目。目前测定空气中二氧化硫的方法归类为离子色谱法、分光光度法、火焰原子吸收光谱法、表面增强拉曼光谱法、催化发光法和现场仪器检测法;其中分光光度法又分为二苯碳酰二肼分光光度法、甲醛缓冲液一盐酸副玫瑰苯胺分光光度法和四氯汞钾一盐酸副玫瑰苯胺分光光度法。本文基于目前工作场所中二氧化硫测定方法的使用情况,分别综述了以上各种方法使用过程中的优势和弊端,以及方法缺陷的改进研究,以期为接下来的方法研究提供参考依据。
Sulfur dioxide is one of the main atmospheric pollutants,which has a strong stimulative effect on respiratory mucosa and eyes and is very harmful to the body.It is not only a routine monitoring project in the meteorological and environmental departments,but also an important occupational disease hazard monitoring project for coal and petroleum petrochemical enterprises.The current methods for determining sulfur dioxide in the air are classified as:ion chromatography,spectrophotometry,flame atomic absorption spectroscopy,surface enhanced Raman spectrometry,catalytic emission,and on-site instrument detection.Based on the current use of sulfur dioxide measurement methods in the workplace,this paper reviews the advantages and disadvantages of the above methods and the improvement of the method defects,providing reference basis for the next research.
