Arsenic Trichloride Filtration Performance with the Impregnated Carbon ASZMT

The vapor filtration of AsCli by the adsorbent ASZMT is examined in this report. Microscalc testing is performed, with analysis of the concentration by FTIR. The effect of humidity on AsCh stability and filtration performance is considered. Large adsorption capacity is determined, approximately 4 mol/kg, by calculating a mass balance from the measured breakthrough results. Hydrochloric acid breaks through prior to AsCh under humid conditions.
