摘要
研究了一种新型二氧化硫被动采样器。考察了无纺布、定性滤纸和定量滤纸等吸收剂的载体在相同情况下对二氧化硫和二氧化氮的吸收效果 ,对吸收载体进行了优选。并针对低温地区和高温高湿的气候条件 ,确立了以三乙醇胺(TEA)为吸收主体 ,分别以乙二醇、丙三醇为添加剂的吸收体系。
A new type of passive sampler for sulfur dioxide monitoring was developed. Different kinds of carriers and absorbents were studied. Triethanolamine was used as the main absorbent with the additives of ethylene glycol and glycerol. The sampler could be used in that area with low temperature or high temperature and high humidity.
