摘要：

Coloration reactions occurring in the pores of porous glass for the detection of NO2 were reported by Tanaka et al[l] and NO2 sensing system based on sol-gel film was depicted by Worsfold et al[2]. In this work, Sulfanilamide(SFA) and N,N-dimethyl-1-naphthylamine, (DMNA) entrapped in an organically modified silicate film, were employed as the diazonzing reagent and the coupling reagent, individually, to detect nitrogen dioxide. The sample gas was prepared by diluting standard NO2 gas with dry N2. The coloration reagents were immobilized in the silicate films first. Then the sensing film was exposed to NO2 in air for ten days.
