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

Abstract

Characterization of activated carbon from oil palm shell prepared by H3PO4and application for the removal of procion red dye was investigated. Oil palm shell was carbonized at 500°C and prepared by H3PO45 % 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-1and 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 H3PO45 % was 278.197 mg g-1which is higher than not chemical activation was 216.456 mg g-1at equilibrium time 5 h.

Characterization of Activated Carbon from Coal and Its Application as Adsorbent on Mine Acid Water Treatment

“…Another researcher reported activated carbon synthesis from coconut shell using phosphate acid as activating agent. Its application on adsorption of red dye Procyon showed the activated carbon has adsorption capacity 278.197 mg/g [6]. Palm oil shell was also used to produce activated carbon using ZnCl2 and physical activation.…”
