Equilibrium Isotherm Models for Adsorption of Zinc (II) Ion from Aqueous Solution on Pulp Waste
Authors: , ,
Abstract: The present investigation deals with the utilization of pulp waste as an adsorbent for the removal of zinc (II) ion from aqueous solution. A series of experiments were conducted in a batch system to evaluate the performance of the pulp waste for zinc removal. The effects of pH, adsorbent dosage, initial concentration and temperature were evaluated. The optimum pH value for zinc (II) adsorption on the pulp waste was found to be pH 6.0. The equilibrium sorption data were analyzed using Freundlich, Langmuir, Temkin, Halsay, Hurkins- Jura, Redlich-Peterson, Dubinin-Radushkevich and Jovanovich isotherm models, and the Langmuir and Temkin models were found to be adequate in describing the zinc (II) adsorption onto the pulp waste.
