摘要：Experimental investigations were conducted on the adsorption characteristics of 2,4 -dichlorophenol by two hypercross-linked resins JP-01 and XAD-4. The static adsorption was studied. Within temperature range of 288-313K, the equilibrium adsorption date was fitted to freundlich adsorption isotherm models to evaluate the model parameters. The enthalpies, free energy, entropy were indicative of an exothermic, a spontaneous and disorder decreasing process. The magnitudes for 2,4-dichlorophenol on JP-01 on XAD-4 show a physical adsorption process. The results showed that the JP-01 adsorbent was better than the Amberlite XAD-4 for removing the 2,4-dichlorophenol in aqueous solutions.
