The dynamic adsorption of trichloroethylene (TCE), 1,2-dichloroethane (DCE) and trichloromethane (TCM) vapors onto hydrophobic hypercrosslinked polymeric resin (LC-1) were investigated using the fixed-bed adsorption method. The results indicated that the breakthrough time decreased and the height of mass transfer zone increased with the elevated initial concentration, gas flow rate and adsorption temperature. The gas flow rate had the wost significant influence on breakthrough time and height of mass transfer zone among the three factors. In addition, a simple semi-empirical mathematic model developed by Yoon and Nelson was applied to investigate the breakthrough behavior, and all correlation coefficients R2 were greater than 0.994.
