Activated carbon is an adsorbent in the separation and purification industries. The adsorption capacity of activated carbon depends on porosity and its surface chemistry. In this review the production of activation carbon from a large number of abundant and low-cost materials and agricultural waste such as Camellia oleifera shell, bamboo, cherry stones, waste tea, and Paulownia flower are discussed. Chemical or physical activation methods and microwave radiation methods are the commonly used techniques adopted for preparation of activated carbon.
