ABSTRACT
Palm fronds are one of the solid wastes from oil palm trees which have a high lignocellulosic content. This indicates that they have the potential to be used as a raw material for magnetic biochar. Magnetic biochar is the result of magnetization of biochar with the addition of chemicals containing metal ions and pyrolysis with little or no oxygen. Magnetic biochar has the potential to be used as an adsorbent which is proven to be able to remove heavy metals such as Cd, Cr(VI) and Pb in solution. This study aims to analyze the effect of the impregnation ratio, pyrolysis temperature, and particle size on the magnetic characteristics of biochar and the adsorption ability of color and organic matter in peat water. Magnetic biochar was synthesized by impregnation using FeCl3.6H2O at a ratio of 0.4; 0.5; 0.6 and 0.7 were pyrolyzed at 450oC and 500oC using N2 gas for 20 minutes with varying particle sizes of 30 and 80 mesh. Magnetic characterization of biochar was carried out by proximate test. In this study the best proximate test results were obtained at an impregnation ratio of 0.7, a pyrolysis temperature of 500oC and a particle size of 80 mesh with a moisture content value of 0.5%, an ash content of 3.37%, a volatile content of 12.02% and methylene absorption. blue 12.4 mg/g. The highest removal of color and organic matter obtained was 71.8% and 78.6% with an adsorption capacity of 4.07 mg/g and a magnetic biochar surface area of 46.05 m2/g.
Keywords : Magnetic biochar, palm fronds, impregnation ratio, pyrolysis temperature, adsorption, peat water.
