Abstract

Biosorption of Cr6+ ions onto raw biomass of the tigernut (Cyperus esculentus) was studied using the batch equilibrium adsorption method. The sorption characteristics of the adsorbent was investigated under various experimental conditions, such as pH, contact time, initial concentration of Cr6+ and sorbent mass. The FT-IR analysis showed that likely functional groups responsible for the adsorption are carboxyl, carbonyl, amides and hydroxyl groups. The pH for optimum adsorption is 3.0 when adsorbent dose is 2.0g at contant time of 15min. Equilibrium data fit well to the Langmuir isotherm. The estimated maximum adsorption capacity was found to be 63.58mg/g at 308°K and 90 .95mg/g at 328°K. Taking into account its good adsorption capacity, ease of sample treatment, as well as availability, the biomass of tigernut is a promising cost-effective biosorbent for Cr6+ removal from aqueous environment.
