Adsorption of lead and different colors from waste water using coconut shells adsorbent in form of simple activated carbon

Abstract

The activated carbon was prepared under limited supply of oxygen from coconut shells as the precursor.The coconut shells are the ones from coconut trees scientifically known as Cocos nucifera, L. Three different pyrolysis temperatures were considered with each three different soaking times investigated. Then also three different activation temperatures were used that is 650, 850 and 1250oC. The effect of the different activation conditions was investigated by comparing absorbance of Methylene blue in samples which had undergone the different conditions.The results strongly indicated that activated carbon used in this study were effective in removing methylene blue with a great reduction of colour and contact time to achieve equilibrium.
