Abstract:

A basic research study was made for specific adsorbents which could be used for the detection of various air pollutants. The most promising adsorbents for various compounds were placed as coatings on a piezoelectric crystal detector, and the device was evaluated as a possible detector for the identification and analysis of these compounds. The nature of the basic reaction of the chemical compounds solids with these pollutants was studied using infrared spectroscopy and oscillating crystals, and the interaction parameters were studied. Quadrol and triethanolamine were good adsorbents for SO2 Co-isonitrolo benzoyl acetone provided an excellent coating for organophosphorus compounds ascorbic acid - AgNO3 was used for assay of NH3, as were Ucon-75-H-90,000 and -Ucon-LB-300X, which were excellent for NH3 and NOx latex and nujol with trans-IrC1COPPh32 were good coatings for aromatic hydrocarbons an acetone extract of a CC14 soot was excellent for the detection of H2S and HC1 was detected using trimethylamine.
