- Аннотация: Porous silica-based monoliths obtained by spinodal phase decomposition of water-tetraethoxysilane mixtures in the presence of polyethylene oxide were tested for pre-concentration of dimethyl methylphosphonate (DMMP) to increase the sensitivity of its detection by semiconductor gas sensors. The best performance in terms of complete adsorption/fast thermodesorption was shown by the sample with a surface area of 280 m2/g. The monoliths with lower surface area were not so effective in DMMP adsorption. while for the samples with higher surface area. the decrease of the sensor signal was observed due to impeded DMMP desorption.
