Technique for adsorption of toxic gaseson metal and salt impregnated cellulose strips

Abstract

Adsorption of CO, NO₂, SO₂, CO₂ gases individually and CO with NO₂ on surfaces of transitional metals and their sulfate, chloride and oxide salts of 100<img src='/image/spc_char/micro.gif'> have been studied. The chemical substances were impregnated on the resin + ethyl cellulose blend coated cellulose strips of 8x3 cm²made of Whatman filter paper 42. The metals and salts (adsorbents) have been impregnated separately on cellulose strip. The dried melamine methylurea formaldehyde polymer resin was blended with ethyl cellulose powder (1:0.05) for higher porosity. The vacant forces of adsorbent develop interaction with gases, as they happen to be the polar and form coordination bond. Thereby weight gain was observed and confirmation was made with IR, SEM and XRF techniques.
