| Abstract |
The potential for physical adsorption as a mechanism for loss of volatile organic chemicals (VOC) and polar volatile organic chemicals (PVOC) from the vapor phase in canister samples was assessed using the principles embodied in the Dubinin-Radushkevich isotherm. A computer-based model was developed for predicting adsorption behavior and vapor phase losses in multicomponent systems based on the potential for physical adsorption as well as the potential for dissolution in condensed water for samples collected at high humidities. At present, the data base for the model contains relevant physicochemical data for 78 compounds (including water), and provisions for inclusion of up to 120 additional compounds are incorporated in the software. |
