Characterization of Activated Carbon from Oil Palm Shell Prepared by H3PO4 for Procion Red Dye Removal

Characterization of activated carbon from oil palm shell prepared by H3PO4 and application for the removal of procion red dye was investigated. Oil palm shell was carbonized at 500°C and prepared by H3PO4 5 % with ratio of 1:3. Characterized activated carbon by Fourier Transform Infra Red Spectroscopy (FTIR), Brunauer Emmet Teller (BET) surface area, Scanning Electron Microscope-Energy Dispersive X Ray Spectrometry (SEM-EDS). The result indicated that functional groups on the activated carbon surface were influenced by acidic treatment. The activated carbon have surface area 385.991 m2g-1 and volume of micro porous 0.201 cm3g-1. The SEM-EDS image showed that activated carbon have many porous structure and the strong peak of C was 92.7 %. Adsorption capacity of activated carbon prepared by H3PO4 5 % was 278.197 mg g-1 which is higher than not chemical activation was 216.456 mg g-1 at equilibrium time 5 h.
