A Study of Gas Solid Reactions.

Abstract

The report summarizes a basic research study undertaken to find specific adsorbents for inorganic and organic gaseous pollutants present in the atmosphere. The basic reaction of chemical compounds (solids) with these pollutants (organophosphoric, organic nitrogen, SO2, NOx, nitrate) was studied using infrared spectroscopy and oscillating crystals. The nature of the interaction between the adsorbent and the pollutant was studied, and the interaction parameters studied. The most promising adsorbents for various classes of compounds were placed as coatings on the piexoelectric crystal detector, and the device was evaluated as a possible detector for the identification and assay of these compounds. The detector and each adsorbent were evaluated with respect to sensitivity and linearity of response, speed of response, accuracy of response, reversibility and limit of detection. Carbowax 20M was found to be a good adsorbent, for SO2 and the FeC13(-)organophosphate complex was good for organophosphorus compounds. A list of publications from the project is included.
