The present invention relates to preparation of activated carbon from leaves, stems and roots of water hyacinth. It relates to a process for obtaining high surface area activated carbon material. More particularly, the invention provides a process for preparing activated carbon which has a pore structure that includes both mesopores and micropores. Activated carbon materials have become widely used as versatile adsorbents owing to their large surface area, micro porous structure, and high degree of surface reactivity. In particular, these materials are especially effective in the adsorption of organic and inorganic compounds due to the high capacity of these molecules to bind to carbon. Activated carbons are commonly produced from materials including coconut shell, wood powder, peat, bone, coal tar, resins and related polymers. Activated carbon has been used in a wide variety of processes, and is extensively used in the process of refining and bleaching of vegetable oils and chemical solutions, water and air purification, recovery of solvents, recovery of gold etc.
