Diffusion and sorption of volatile organic compounds in indoor surface materials
An experimental set-up that enables the determination of diffusion coefficients and sorption capacities of volatile organic compounds (VOCs) in indoor surface materials is presented. n-octane and ethyl acetate were studied in gypsum board, carpet, aerated concrete, solid concrete, brick wall, wallpaper with paste, acrylic paint on woodchip paper and polyvinyl chloride (PVC) floor covering. The material to be tested was placed between a pair of small test chambers of Climpaq type. Air with a constant concentration of an added VOC was introduced into one chamber and clean air into the other chamber. Concentrations were measured on both sides of the material with a photoacoustic detector.
