Specification of Activated carbon / Karbon aktif
Activated carbon
Activated carbon is a form of charcoal that has been through activation by using CO2 gas, water vapor or chemicals so that the pores are exposed and thus the absorption power becomes higher to the substance, color and odor. Activated carbon contains 5 to 15 percent water, 2 to 3 percent ash and the remainder consists of carbon. Amorphous amorphous carbon is composed of flat plates, arranged by C atoms bonded covalently in a flat hexagonal lattice with one C atom at each angle. The plates are stacked together to form crystals with residual hydrocarbons, tars and other organic compounds left behind on the surface. The raw materials of activated carbon can be derived from vegetable materials or derivatives and animal materials. The quality of the activated carbon produced from the coconut shell has a high absorbency, because the char is porous with a small diameter, so it has a large internal. The surface area of the charcoal is 2 x 104 cm2 per gram, but after the activation with chemicals it has an area of 5 x 106 to 15 x 107cm2 per gram. There are two main stages of the process of making activated carbon that is the process of carbonation and the process of activation. It is explained that in general the process of perfect carbonization is heating raw materials in the absence of air to a sufficiently high temperature to dry and vaporize compounds in carbon. In this process there is a thermal decomposition of a carbonaceous material, and removes the non-carbon species. The activation process aims to increase the volume and increase the pore diameter after undergoing carbonization, and increase absorption.
