Abstract

Activated carbon as one of the widely used adsorbent has many application in the environment for the water purification and removing pollutant. Activated carbon can produced from agricultural waste and has not been optimally used. In this paper, these natural sources from agricultural waste materials has been reviewed and the potential as activated carbon. Characteristics of activated carbon that can be used as a activated carbon depends on surface area and pore structure prepared through activation method. Activation method for carbon depends on the precursor and characteristic of activated carbon which are expected. Natural sources can be converted into activated carbon by chemical, physical, or physical-chemical activation. Therefore, this paper is aimed to providing information about methods of production activated carbon has been reported for purify water.

Abstract

Biosorbent derived from agricultural waste as one of the widely used adsorbents has many applications in the environment to remove pollutants, one of which is heavy metal copper (Cu). In this paper, natural sources of agricultural waste materials have been reviewed and have potential as biosorbents for the absorption of heavy metal copper (Cu). The characteristics of the biosorbent that can be used for the absorption of heavy metal copper (Cu) depend on the surface area and pore structure made by the modified method. The biosorbent modification method depends on the precursor and the expected biosorbent characteristics. Natural biosorbents can be converted into modified biosorbents by chemical, physical, or physico-chemical modifications. Therefore, this paper aims to provide information about the absorption of adsorbents from agricultural wastes that have been reported for the absorption of heavy metal copper (Cu) in wastewater
