Absorptive Efficacy Analysis of Lignocellullosic Waste Carbonaceous
Absorbents towards Mercury species
Name: Sharyar Jeelani
Abstract
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 Hg2
+ absorption into lignocellulosic char was less than activated carbon, however , an opposite
result was studied in MeHg+ indicating that both the mercury species interact with the surface
differently.
