Utilization of activated carbon in combination with ionic liquids for removal of halogenated dyes growing parameter AOX from model waste water

Abstract

This work deals with the removal of chlorinated acid dyes such as Mordant Blue 9 and Acid Yellow 17 from model wastewater using granular activated carbon and ionic liquids. In this work, comparison of granular charcoal adsorption efficiency with subsequent effect of added aqueous mixture of benzylalkyldimethylammonium chloride (benzalkonium chloride) with methyltrialkylammonium chloride (Aliquat 336) on mentioned dyes removal efficiencies was studied. It was observed that addition of ionic liquid to the saturated active carbon enables enhancement of sorption capacity of this adsorbent.
