Reduction of Acidic Pollutant Gases inside Showcases by the Use of Activated Carbon
نویسندگان
چکیده
Activated carbon adsorbing materials were installed in a number of showcases with heritage objects belonging to English Heritage. The reduction of acetic plus formic acid concentration in air, which could be achieved by the installation of the different adsorbing materials, was investigated. The concentrations of the gases were measured before and after installation of the adsorbers. The reduction in the acetic plus formic acid concentration depended both on the activated carbon adsorbing material which was installed, and on the ventilation rate of the showcases.
