ABSTRACT

The present works show a preparation of novel adsorbent. The noveladsorbent was prepared from carbon based on a native lignocellulosicprecursor. The precursor chosen for preparation of novel adsorbent wasnatural and easily available plant (Glycosmis Mauritania) fromagricultural land. The activation process was carried out by twodifferent process physical activation and chemical activation. Chemicalactivation was carried out by dipping the plant materials in differentactivating chemicals like phosphoric acid, sulphuric acid, potassiumhydroxide and zinc chloride at certain concentration for 24 hours. Thecarbonization process of the precursor was carried out at 4000C and theactivation taken at 6000C using muffle furnace for both physical andchemical activation. The prepared novel adsorbent was further made to characterize itsphysico-chemical parameters to determine the nature of the adsorbent. The surface group andsurface morphology of the adsorbent can be identified using HRSEM and FTIR spectroscopy.Surface area of the activated carbon can be calculated by using nitrogen adsorption.
