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 v olatile organic compounds have been investigated. A limited number of experiments have been conducted to investigate the influence of parame ters such as the adsorption time, the desorption time, the concentrati on 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 g uide screening method can be applied with mixtures of VOCs with a limi ted adsorption time and desorption time (6 h each). Air samples should be collected at the end of the adsorption time and during the desorpt ion time. (C) Indoor Air (1998).
