Activated carbon is an adsorbent fabricated from a variety of carbonaceous source materials. It is used as an adsorbent for removal of organic compounds from air and water streams owing to surface area and porosity. In this study, activated carbon was prepared from microalgae by chemical activation with adjusting KOH/char ratios from 1 to 5 for high surface area and porosity. The physicochemical properties of activated carbon derived microalgae were characterized by thermogravimetric Analysis, Scanning electron microscope and Boehm titration methods. The porosity of materials was made up of uniform micropores, most of them having sizes ＜1 um. |
