The presence of mercury in water has been of great public concern. Mercury because of its carcinogenic and mutagenic nature is very harmful to human and animal life. Not only mercury but various other compounds formed from mercury have proven quite harmful to human beings. Mercury is emitted into atmosphere by metal smelting, coal combustion and water incineration. Several methods have been developed for removal of mercury from water such as precipitation, adsorption, membrane separation, filtration and biological treatment. Of all these processes adsorption has been found more effective because of economical and effectiveness especially for low mercury concentration. Activated carbon have been widely used industrially due to effective applications for treating various types of pollutants. Now the absorptive efficacy of lignocellulosic waste char and activated carbon towards inorganic hg2+ and organic MeHg+ ions was studied. Activated Carbon and lignocellulosic waste were, respectively, prepared by carbonization and KOH activation process of lignocellulosic waste carried out at 700 C. The Hg
