Abstract
Dyestuff waste can cause water pollution. One of them is cationic dye waste that is difficult to remove because it has a complex composition and innert, so it needs to be treated before being released freely into the water sources. The manufacture of carbon from sugar palm fiber waste is a new innovation in science that can produce adsorbents to dyes waste adsorption in water sources, and also to increase the value of sugar palm fibers. Carbon from sugar palm fibers (Arenga pinnata) were modified with iron oxide with concentrations 3% in 1 gram of carbon. Carbon were made by carbonizing sugar palm fiber at a temperature of 300oC for 2 hours, then the carbon activated with 3M H2SO4 and then carried out by wet impregnation with Fe(NO)3.9H2O and calcined at the various temperature: 200oC- 300oC- and 400oC for 2 hours to produce reddish black powder. The characterization of FTIR and XRD showed peaks corresponding to existence of Fe2O3, whilst the SEM image also suggesting of presence of Fe2O3.
