dc.description.abstractBarley straw (BS), a very low-cost material, has been utilized as a biosorbent material for the removal of copper (Cu2+) ions from aqueous solutions after treatment with citric acid. Barley straw was thermochemically modified with citric acid (CA-BS) for the purpose of improving the Cu2+ ion sorption capacity of the straw. Biosorption studies have been carried out to determine the effect of pH, adsorbent concentration, contact time, extent of modification, and adsorbate concentration on the biosorption capacity of Cu2+ ions by the esterified straw. The equilibrium sorption capacities of Cu2+ were 4.64 mg/g and 31.71 mg/g for BS and CA-BS, respectively. The optimum pH for the removal of Cu2+ ions by CA-BS was around pH 7.0 and the removal of Cu2+ ions was 88.1%. Langmuir. Freundlich, Scatchard and D-R (Dubinin-Radushkevich) isotherms have been used to characterize the observed biosorption phenomena of Cu2+ ions on CA-BS. The carboxyl groups on the surface of the modified barley straw were primarily responsible for the sorption of Cu2+ ions. (C) 2012 Elsevier Ltd. All rights reserved.en_US
