Absorption of Doc and Fe Activated Carbon Coconut Palm Oil Activation Results using H3PO4 Chemicals with Grain Size and Longer Immersion

Abstract
Palm oil shells can be useful as raw material for making activated carbon because they are very effective at adsorbing contaminants in water. Activated carbon is one of the adsorbents which has adsorption power. Adsorption power is the ability to absorb. The aim of this study was to determine the absorption capacity of activated charcoal by immersing H3PO4 and grain size of Mesh 200 palm oil shells. Variables observed were sorption and release DOC and iron (Fe) sorption. Analysis to get the sorption power and release of DOC is done. Making stock DOC solution, DOC sorption experiment, DOC sorption is analyzed using isotherm linear initial mass (IM) approach, and to get iron sorption (Fe) is done by making Fe concentration concentration, iron sorption experiment (iron sorption experiment) Fe), the concentration of iron (Fe) in the filtrate is determined by AAS., Then presented in tabular and graphical form. The results of the maximum sorption and release of DOC were 0.9119 mg / l / kg, while the maximum iron sorption (Fe) was 0.959 mg / l / kg.
