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.
We prepared activated carbon from empty oil palm bunches by modifying the metal (Fe and Cu) in the structure of the activated carbon. Empty oil palm bunches obtained in Padang Bulan, Medan, North Sumatera and after washed, it mashed then heated at 500 °C for 1 minutes. For modification, activated carbon was dissolved in a 0.1 M solution of Fe(NO3)2 and Cu(NO3)2 which is heated at 60 oC for 3 hours. Activated carbon without and with modification was then characterized using XRD and SEM / EDX. The XRD results showed slighly change after modification with new peaks appearing and missing peaks. SEM images also show that the activated carbon before modification is irregular in shape, while the activated carbon after modification is more regular and homogeneous. The presence of Fe and Cu on the modified activated carbon is also evidenced by the EDX image, which shows the presence of Fe and Cu peaks when compared to activated carbon before modification which does not show the presence of Fe and Cu metals. It successful to modified Fe and Cu inside the activated carbon of empty oil palm bunches which consider to improve their adsorption properties.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
