Abstract

Recently, as people's interest in environmental pollution increases, interest in indoor air pollution as well as outdoors is increasing. Accordingly, this study prepares functional paints by mixing powder activated carbon, which is a porous material, into aqueous paints, and examines the adsorption performance of volatile organic compounds (VOCs) and formaldehyde (HCHO). As a result of the experiment, the concentration of volatile organic compounds (VOCs) and formaldehyde (HCHO) tended to decrease as powder activated carbon was incorporated. It is believed that physical adsorption was achieved by the micropores of powdered activated carbon. However, in the adsorption test method, it is judged that the concentration was affected by the inflow of outside air as the chamber cover was opened to put the test object in the empty chamber where a certain concentration was maintained.
