Stoichiometry of nitrogen dioxide determination in triethanolamine trapping solution

Abstract: made with our present Fourier transform spectrometer in this spectral region. At most, only one point jitter (0.03 nm) is observed and all wavelengths are accurate to 0.07 nm or better.Further studies on the application of Fourier transform spectrochemical instrumentation to atomic spectrochemical measurements are continuing in our laboratory. These studies include the assessment of the simultaneous multielement analysis capability of our system (both qualitative and quantitative) utilizing flame, dc arc, and … Show more

“…O mecanismo da reação de TEA com NO 2 ainda não está bem estabelecido, mas a estequiometria proposta para NO 2 em solução aquosa fornece uma relação molar de 2NO 2 :1TEA (Equação 6). 26 Como foram utilizados 80 µL da solução absorvente (11% v/v TEA, com densidade de 1,13 g mL -1 e 140 g mol -1 ), cada filtro impregnado contem cerca de 60 µmol de TEA. Isto significa que, considerando-se eficiência de coleta de 100%, seria possível reter cerca de 120 µmol de NO 2 ou cerca de 3000 µL de NO 2 a 25 °C.…”

“…The reaction-product of TEA has been subjected to several investigations (Aoyama and Yashiro 1983;Gold 1977;Haue-Pedersen et al 1994;Levaggi et al 1972;Palmes et al 1976). Results lead to the identification of TEA N-oxide as a reaction product Protective cover Radiello (2006) micro-porous polyethylene for outdoor sampling a Rates calculated by Tang et al (2001) with the 1:1 conversion of NO 2 to nitrite ions (Glasius et al 1999;Palmes and Johnson 1987).…”

“…The sensitivity and utmost accuracy of this particular tube length and the selectivity and specificity of triethanolamine for NO 2 have been documented. 17,18 In preparing the tubes, uniformity was maximized, for example, the same dying time for each of the steel grids, and the use of a freshly prepared triethanolamine/acetone mixture. The required steel grids were cleaned with acetone and dried properly.…”
