A Quick Screening Method for Sorption Effects of Volatile Organic Compounds on Indoor Materials

Sorption effects of a number of combinations of indoor materials and volatile organic compounds have been investigated. A limited number of experiments have been conducted to investigate the influence of parameters such as the adsorption time, the desorption time, the concentration of the pollutants and the temperature, on the sorption. Experiments were performed with vapours of single compounds and with mixtures of VOCs. All parameters have an influence on the sorption. A relatively quick screening method can be applied with mixtures of VOCs with a limited adsorption time and desorption time (6 h each). Air samples should be collected at the end of the adsorption time and during the desorption time. © Indoor Air (1998).
