| Abstract: | A method enabling the calculation of a series of adsorption isotherms of volatile organic substances at different temperatures was introduced based on a few temperature-programmed desorption(TPD) experiments.In the method,a transient kinetic model was established based on quasi-equilibrium adsorption/desorption between the gas phase and the adsorbent for the rapid readsorption during TPD.The model was numerically solved to fit to experimental TPD data by adjusting the equilibrium parameters.Hence the adsorp... |
