Abstract

A granular activated carbon (GAC) modified by cationic surfactant cetyltrimethylammonium chloride (GAC-CTAC) was investigated for its adsorption of oxyanions (perchlorate, bromate, arsenate, nitrate, sulfate and phosphate). GAC-CTAC showed adsorption capacities 4-7 times those of virgin granular activated carbon. The free energies of adsorption by virgin granular activated carbon and GAC-CTAC showed that cationic surfactant modification changed the interaction between adsorbent and adsorbate. Ion exchange played a major role in adsorption with GAC-CTAC. In addition, GAC-CTAC showed different levels of selectivity towards oxyanions. Results reveal that GAC-CTAC was more selective towards perchlorate, bromate and nitrate than arsenate, sulfate and phosphate. Moreover, selectivity was highly dependent upon oxyanion's free energies of hydration and adsorption.
