Description
Lead is one of the major pollutants in wastewater. It is used as a major raw material in battery manufacturing and industrial effluent from this industry can contain high concentration of lead. In this research, removal of lead from this industrial effluent has been investigated by using coconut shell sulphonated and nitrated carbon from carbonized coconut shell powder. Carbonization temperatures were 300ºC, 400ºC, 500ºC, 600ºC, 700ºC respectively at resident time of 10 minutes. Determination of yield %, the most suitable temperature, as well as ash content, moisture content, volatile matter content, fixed carbon content and iodine adsorption activity of carbonized carbon were studied. The most suitable carbonization temperature was found to be 500ºC. Carbonized powdered carbon (500ºC) was activated with various concentrations of sulphuric acid and nitric acid for 24 hour. Effect of various parameters such as acid concentration (1N, 1.25N, 1.5N, 1.75N, 2.0N) for activation on adsorption efficiency of sulphonated and nitrated carbon was characterized by iodine adsorption activity and methylene blue decolorizing power. It was found that carbon activated by 1.5N sulphuric acid and nitric acid had the most favorable for adsorption. Effect of pH of battery industrial effluent and amount of sulphonated and nitrated carbon on removal of lead from battery industrial effluent were determined. Amount of lead in industrial effluent before and after treatment were measured by Atomic Absorption Spectrophotometer (AAS). It was found that the maximum removing efficiency of lead by 200 mg of sulphonated carbon was 96.3% and that of nitrated carbon was 97% for industrial waste water at pH 6. The result indicated that acid treated carbonized coconut shell powder could be used as high capacity adsorbent for the removal of lead from industrial effluent.
