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