Adsorption And Removal Of Cu (ii) Ions Onto A Starch Film Sorbent From Aqueous Medium
Résumé: The biosorption capacity of sorbent starch-based films prepared by solution casting method from aqueous solution was investigated. Batches studies are carried out and the key processing parameters (sorbent quantity, contact time, metal ion concentration, temperature and acidity of the adsorbate solution.) were studied. The adsorption condition of Cu(II) metal ions onto starch biodegradable film have been studied, FTIR spectra, UV adsorption and PH measurements before and after adsorption demonstrated that the hydroxyl, carboxyl, and carbonyl groups are responsible for the biosorption process, the adsorbed amounts of copper was 79,8,% of the total concentration of the metal ions. The best adsorption capacities were 5,44mg/g at optimum conditions. All the above results demonstrated that starch based films are generally regarded as safe and environmentally acceptable, and this bisorbents films can be used as a possible alternative low-cost adsorbent for the removal of heavy metals from aqueous solution.
