摘要

An experimental comparison of the adsorption properties of hypercrosslinked resin AM-1 modified by phenolic hydroxyl group with Amberlite XAD-4 toward 2

4-dichlorobenzoxyacetic acid was performed. This paper focuses on the static equilibrium adsorption behaviors and the adsorption thermodynamics. Two isotherm models were used to explain the results. It is seen that the Langmuir equation can give a perfect fit. The adsorption capacities from the different ranges of temperature

the adsorption enthalpy change value and the comparison of desorption conditions lead to the same conclusion that the adsorption of 2

4-dichlorobenzoxyacetic acid from water onto AM-1 is a type of physical and chemical transition.
