Abstract

Since decade ago, water pollutants became a big concern as there are many impacts on human health that may contribute to any health issue. Activated carbon can be used to regulate water contaminants. In both liquid and gas, activated carbon allows poison, insecticides, bad odor, taste, heavy metal, and undesirable elements to be trapped. In addition, several experiments have been carried out on oil palm shells in various applications of activated carbon to control emissions. In order to achieve the highest absorption of air and water emissions, shorter processing time, low cost and a wide variety of usable applications, the method of activated carbon production is used through chemical, thermal or physical processes but at an acceptable temperature to the produced chemical. The focus of this research is to study activated carbon prepared using oil palm shells by thermal and physical activation through the use of to generate high absorption activated carbon provided by a higher specific surface area and to characterize the oil palm shell derived activated carbon. In previous researches, activated carbon were prepared using common wood. Some problems faced by the wood decomposition process that occurs due to warming in the dry distillation process. By using the oil palm shell as the new raw material to generate more effective activated carbon, the weakness face by wood material can be strengthened and has better properties than commercially available activated carbon. Nevertheless, as many researchers concentrating on chemical activation, there has been limited research to date on the method of thermal activation by using oil palm shell. The surface morphology and effect of activated carbon pH has been set as a parameter for the collection and analysis of activated carbon. The surface morphology before and after the activation process of carbon structure and the pore widening impact due to the temperature expected to be present. Activated carbon prepared of 600 ℃ of activation process was selected as the best sample sample as it is yield high burn-off degree of 74.71 wt%, wider pore as shown by micrograph structure and performed the best water filtration of pH 7. Thus, compared to other inorganic materials, activated carbon from oil palm shell could be the favourable global market for its water application efficiency and low potential cost material.
