STUDY OF POLLUTANT GAS-ADSORPTION ON ACTIVATED-CHARCOAL USING FTIR SPECTROSCOPY

In this study, the efficiency of an air cleaning system, using activat ed charcoal cartridges, which must operate in a confined atmosphere wi th particularly high air flow rate, is tested. A device which generate s dynamic polluted atmospheres is described. A continuous quantitative analysis is made by means of the Fourier Transform Infrared Spectrosc opy (FTIR). The pollutants studied are : carbon monoxyde (1500 ppm), s ulfur dioxyde (100 ppm), nitrogen dioxyde (50 ppm) and hydrogen chlori de (500 ppm). Gas adsorption kinetics on activated carbon are given an d discussed by using breakthrough curves.
