Study on adsorption performance of phenol with hypercrosslinked resin modified with salicylic acid

LI Lou-gang

Abstract

Hypercrosslinked polymeric adsorbent modified with salicylic acid(SYS) for adsorbing phenol was prepared.The static adsorption and kinetic characteristics for phenol onto SYS were investigated.Three adsorption equations were employed to fit the static data.The first order kinetics equation and the second order kinetics equation were employed to fit the dynamic data.The result shows that physical adsorption and chemical adsorption exist in the adsorption processes of SYS resin for phenol at the right temperature.The adsorption process was fit for the first order kinetics equation.
