Description:
A mathematical model was developed for describing loss by physical adsorption of volatile organic chemicals (VOCs) and polar volatile organic chemicals (PVOCs) in stainless steel canisters. he model incorporates compound specific properties such as polarizability, vapor concentration, temperature, and equilibrium vapor pressure. xperimental results show that the model correctly predicts the loss of VOCs in canisters from very dry samples. isting which documents the software program that implements the model is included in the report. ith the program, a user can predict the stability of VOCs and PVOCs in multicomponent mixtures including water vapor under user-specified conditions of temperature and pressure. hysicochemical data needed for the model are provided for more than sixty compounds.
