Presence of heavy metals in water poses a very serious environmental concern since these metal ions are toxic to human beings. It has been significantly observed that the low-cost agro-based waste material exhibits great potentiality to be used as adsorbents for the removal of toxic metal ions from waste water. This paper presents a review of the available literature using agro-based waste material for the removal of heavy metals, Chromium and Mercury in particular.
