摘要

Abstract

Self-made kaolin/sodium lignosulfonate graft acrylic acid and acrylamide superabsorbent composites (KLPAAM）were used to measure the adsorption properties in CuCl2 and ZnCl2 salt solutions

and their adsorption mechanism was discussed by using FTIR

SEM and adsorption kinetic simulation.The adsorption capacities of KLPAAM for Cu2+ increased with increasing initial concentrations of Cu2+ and then decreased

while the adsorption capacities of KLPAAM for Zn2+ increased with increasing initial concentrations of Zn2+ and then tended to reach an equilibrium value

and the relation fitted the Langmuir equation.The maximum adsorption capacities for Cu2+ and Zn2+ were 180 mg·g-1 and 169 mg·g-1 respectively.The pH values obviously affected the adsorption of KLPAAM for heavy metal ions.The adsorption capacities increased with increasing solutions pH values at 2.55.5.The adsorption kinetic equation of the relation between the adsorption capacities of KLPAAM for Cu2+ and Zn2+ and the adsorption time satisfied the pseudo-second order adsorption rate equation.
