Synthesis and Characterization of Activated Carbon for removal of Pb

Activated carbons are unique and versatile adsorbents because of their extended interparticulate large surface area, microporous structure, high adsorption capacity and high degree of surface reactivity. Depending on the functional group and ions present on the surface of the activated carbon, its adsorption quality varies. However, high cost and non-renewable source of commercially available Activated Carbons limits its use as an adsorbent. This has led to the search for low cost feedstock as raw materials for the synthesis of activated carbons. Activated carbons prepared from locally available biowaste such as the stem and leaves of common bamboo and common Buckwheat have been successfully demonstrated for the removal of lead and Manganese ions from water.
