Preparation and characterization of activated carbons derived from marine green algae ulva fasciata sp.

Abstract

In present study, activated carbons were prepared from marine green algae Ulva fasciata sp. by chemical activation process and compared with the commercial activated carbon. Their characteristic properties such as moisture content, volatile matter, ash content, fixed carbon content, matter soluble in water, matter soluble in acid, pH, bulk density, decolorizing power, iodine value, elemental analysis and surface area have been studied. Activated carbons prepared from marine green algae Ulva fasciata sp. have large amount of surface chemical groups present in the sample are good anchoring sites for adsorption. The microstructure of the prepared activated carbons was examined by SEM analysis, while the FTIR spectra analysis showed the surface functional groups and X-Ray fluorescence analysis showed oxide forms of elements present in the activated carbons.
