Cassava Peels Waste Becomes Activated Carbon - A Literature Review

The purpose of this literature review is to determine the effect of acid, salt, and alkaline activators as well as the effect of activated carbon particle size on the quality of activated carbon from cassava peel waste following SNI No. 06-3730-1995. Cassava peel waste is used as raw material for making activated carbon because it has a carbon content of 59.31%. In general, the manufacture of activated carbon from cassava peels is carried out through three main stages, namely dehydration, carbonization, and activation. Activation is needed to obtain high adsorption power. The activators that are the focus of this literature review are H3PO4, ZnCl2, NaCl, Na2CO3 dan KOH. The main source of literature used is research that discusses the manufacture of activated carbon from cassava peels. The results showed that the activator used to produce the best quality activated carbon was the acid activator, namely H3PO4 with a concentration of 2.44% and a particle size of 100 mesh. The resulting activated carbon has a moisture content of 3.5%, an ash content of 7.5%, and an iodine number of 2537.71 mg / g. Based on the results of the analysis, this activated carbon fulfilled the quality of activated carbon based on SNI No. 06-3730-1995.
