Abstract: This study evaluates the use of triethanolamine (TEA) as an alternative to routinely used active carbon employed as a coating for collecting NO2 on a diffusion denuder. The study is based on laboratory experiments made by using annular diffusion denuders coated with TEA. The pre-exponential and exponential factors for the first term of the Gormley-Kennedy equation applied to annular geometry were estimated and compared with the corresponding values for other coatings used in previous studies published in the literature. It was found that TEA does not behave as a perfect sink in comparison with other coatings such as treated active carbon and alkaline guaiacol.
