| Abstract: | Activated carbon prepared from tamarind seeds is used to adsorb selected heavy metals such as chromium and Iron ions and oxalic acid and the adsorption capacity of activated carbon from tamarind seed was compared with the adsorption capacity of commercially available activated charcoal.Tamarind seeds which is an agricultural wastes and also waste product in many industries was activated with sulphuric acid and then used for the removal of these toxic metals from their aqueous solutions.The effects of varying the adsorbent dosage, contact time, pH of the solution mixture of adsorbent and toxic material on the adsorption capacity of the activated carbons were determined. The characterization of activated carbon was analysed by FTIR.The batch experiments were conducted for different adsorbent dosage , contact time and different pH. Adsorbent dosage of 2.5 g gave the Maximum adsorption for all the three toxic materials (chromium, Iron and oxalic acid).Adsorption of materials increases with increase in the adsorbent dosage. At lower pH, more adsorption of metals was observed. Maximum adsorption took place in the pH range of 3-5. With increase in the agitation time or contact time, the adsorption of metals also increased. Optimum adsorption occurred at 5 hr contact time.Adsorption studies are carried out with commercial activated carbon and are compared with the results obtained from tamarind seed activated carbon. But considering the overall economics activated carbon from tamarind seed gives better results of adsorption. |
