Activated carbon is a solid carbon compound that composed of carbon in the form of charcoal and the activated carbon plays a major role in some industrial applications such as the water purifications and air purification because of the strong adsorption of the surfaces of activated carbon with the pores and tend to remove some volatile organic compounds (VOC) and most of contaminants from the water, air or some other material. Usually various materials are used in the manufacturing of activated carbon including different woods and some kinds of synthetic materials. According scope of the nouveau research, there were expected to manufacture activated carbon using disposable coconut shells. The coconut shells were burnt using a muffle furnace while adjusting a range of temperatures in 300 °C - 390 °C for a few sets of coconut shells. The elemental compositions of manufactured activated carbon were analyzed using X-ray fluorescence (XRF) spectrophotometer and also the surfaces of manufactured activated carbon were microscopically analyzed using an optical microscope. There were identified the range of 330 °C - 350 °C as the most adequate temperatures for the manufacturing process of activated carbon from these coconut shells, 68.85% of Fe and 31.15% of K as the composed metallic elements in addition to the non metallic carbon.
