limited application because they often involve high
capital and operational costs. Adsorption is an effective
and versatile method for removing chromium. Natural
materials that are available in large quantities, or certain
waste products from industrial or agricultural operations,
may have potential as inexpensive sorbents. Due
to their low cost, after these materials have been expended,
they can be disposed of without expensive
regeneration. Most of the low cost sorbents have the
limitation of low sorptive capacity and thereby for the
same degree of treatment, it generates more solid waste
(pollutant laden sorbent after treatment), which poses
disposal problems. Therefore, there is need to explore
low cost sorbent having high contaminant sorption
capacity
