Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"> Iron is a major pollutant released as a by-product during several industrial operations especially during acid mining of metal ores. In this paper, the use of Bengal gram husk (husk of channa dal, <i style="">Cicer arientinum</i>) in the biosorption of Fe(III) from aqueous solutions is discussed. Parameters like agitation time, adsorbent dosage and <i style="">p</i>H were studied at different Fe(III) concentrations. The adsorption data fit well with Langmuir and Freundlich isotherm models. The adsorption capacity (<i style="">q</i><sub>max</sub>) calculated from the Langmuir isotherm was 72.16 mg of Fe(III)/g of the biosorbent at an initial <i style="">p</i>H of 2.5. Desorption studies were performed at different concentrations of hydrochloric acid showing that quantitative recovery of the metal ion is possible. The infrared spectra of the biomass before and after treatment with Fe(III), revealed that hydroxyl, carboxyl and amide bonds are involved in the uptake of Fe(III) ions. </smarttagtype>
