Characterization of Cassava (Manihot esculenta Crantz) Peel Activated Carbon based on Impregnation Ratio and Activation Temperature

Cassava peel is a natural material that still underutilized even though has the potential as an alternative to activated carbon precursors. In synthesis of carbon, impregnation ratio and activation temperature are important factors affect characteristics produced. This study aims determine effect variations in (carbon: H3PO4) on from cassava (CPAC) optimal conditions manufacture CPAC. this study, CPAC was produced by treatment with various ratios 1:5, 1:6, 1:8, 1:10, 1:12 (w/w, carbon: H3PO4 30%) range variation 400 - 800 °C furnace for 60 minutes. The results were analyzed using FTIR, XRD, SEM-EDX instruments. Based FTIR test, it showed contain functional groups O–H, C–H, C≡C, C=C, C–O/P=O 1:6 500 minutes be production amorphous crystalline character based XRD analysis hollow (porous) surface SEM analysis. EDX test consisted elements (C), oxygen (O), nitrogen (N), phosphate (P), sodium (Na) respective percentages being 72.60%, 15.52%, 10 .32%, 1.09%, 0.47% respectively.
