Study on the Adsorption of 2-chlorophenol onto the Hypercrosslinked Adsorption Resin Modified by Salicylic Acid

Zhenghao Fei

Abstract

Studies on the adsorption thermodynamics and kinetics of 2-chlorophenol by SYS resin modified by salicylic acid was carried out through static experiments at at different temperature.And the adsorption data was fit for the Freundlich and Langmuir adsorption isotherm.The result shows the adsorption of 2-chlorophenol on SYS resin is an exothermic sorption process which runs spontaneously,and the adsorption of 2-chlorophenol on SYS resin is carried out in two regions of the macropore/mesopore region and the micropore one while the adsorption rates in the two regions both fulfil the first order kinetics.
