Activated carbon can be used for removal of organic chemicals, chlorine, lead, unpleasant tastes and odors in effluent or coloured substances from gas or liquid streams by the mechanism of adsorption. Adsorption can be classically defined as absorption on the surface of the material due to capillary condensation inside the multitude of pores and active sites available. Modern water purifiers come with activated carbon filter. Activated carbon water is very effective in removing chlorine from water which is cancerous if consumed.
High-grade activated carbon can be obtained from woody material like bamboo having inherent mechanical strength, high carbon and low ash content. Since India is the second largest producers of bamboo, there exists an excellent scope for producing bamboo based high-grade activated carbon if appropriate technology is developed and exploited at commercial level.
