What is Activated Carbon?

Activated carbon is carbon base that has been treated to have remarkable pore volume for foreign substance adsorption. Activated carbon can be made from various materials with high carbon content such as coconut shell, palm shell, wood charcoal or coal. Raw material has a large impact on the characteristics and performance of activated carbon. Coconut shell activated carbon has a very high number of micro pores which is good for the removal of smaller organic compounds with strong odors and dechlorination application. On the other hand, wood based activated carbon suits for color removal due to its higher number of meso and macro pores inside.

One of the processes producing activated carbon is activation. Charcoal or carbonized material will be processed at high temperature, about 900-1200 degree Celsius, with oxygen controlling and converted to activated carbon. 1 gram of activated carbon has a total surface area more than 500 m3 which can be determined by several methods. The most common one is the adsorption of iodine known as iodine number. (activated carbon indonesia)
