title: Activation Methods of Carbonaceous Materials Obtained from Agricultural Waste.
abstract: Activated carbons belong to the most widely used adsorbent materials. The utility of these materials mainly depends on their chemical surface and porous structure. The method of activation and the nature of the used precursor greatly influence the pore structure and surface functional groups of the activated carbon. Therefore, the main objective of current investigations is to develop or modify the activation method in an optimal manner using appropriate precursors. This review compiles the results of various studies on the synthesis of activated carbons from agricultural waste. Various activation methods, such as physical, chemical, physicochemical, and microwave activation, are discussed. The effects of carbonization and activation parameters, such as temperature, activating agent, and residence time, toward the properties of the activated carbon are reviewed.
