title: Adsorption equilibria and kinetics for the adsorption of p-nitrophenol on a phenoxy groups modified hypercrosslinked polystyrene resin.
abstract: Adsorption equilibria and kinetics of p-nitrophenol adsorbed on HJ-01 were investigated in this study. The result indicated that phenoxy groups were uploaded on the skeleton of HJ-01 successfully, the Friedel-Crafts reaction brought on prodigious changes for the Brunauer-Emmett-Teller (BET) specific surface area and pore structure while the nucleophilic substitution reaction had few effects. The adsorption experiments revealed that the acidic solution was suitable for p-nitrophenol adsorption, the adsorption isotherms could be characterized by the Freundlich isotherm equation and the adsorption thermodynamic parameters were all negative, the adsorption kinetic curves obeyed the pseudo-second-order rate equation.
