| Abstract: | 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. |
