Description :
Adsorption is a process that occurs when a gas or liquid solute accumulates on the surface of a solid or a liquid
(adsorbent), forming a molecular or atomic film. Adsorption is operative in most natural physical, biological, and
chemical systems, and is widely used in industrial applications such as activated charcoal, synthetic resins and
water purification. Among these methods, adsorption is currently considered to be very suitable for wastewater
treatment because of its simplicity and cost effectiveness. Adsorption is commonly used technique for the removal
of metal ions from various industrial effluents. Activated carbon is the most widely used adsorbent.
