Abstract

The use of unmodified and carboxymethylated granular activated carbon (GAC) for adsorption of Hg2+ and Ni2+ from aqueous solutions was assessed in this work. The effect of concentration and modification by carboxymethyl group on the adsorption of these metal ions was studied in batch process. The adsorption data were correlated with Langmuir, Freundlich, Dubinin-Radushkevich and Temkin isotherm models. Results show that Freundlich model gave the best description for the adsorption process followed by the Langmuir model. Langmuir adsorption capacity corresponding to sites saturation was found to be 20.83 mg g-1 and 19.05 mg g-1 for adsorption of the Hg2+ and Ni2+ respectively onto the unmodified adsorbent and 19.72 mg g-1 and 17.01 mg g-1 for adsorption onto the carboxymethylated substrate. The apparent energy values obtained from the Dubinin-Radushvich model further indicates that the forces of the adsorption follow physical mode. Modification by carboxymethyl group generally caused a decline in the adsorption capacity by the adsorbent. Results obtained generally showed that Hg (II) ions were better adsorbed onto both adsorbents as compared to Nickel (II).
