Oil Palm Trunk Activated Carbon for the Removal of Tannin, Acid Blue 25, and Sunset Yellow: Synthesis, Kinetics, and Isotherms

Activated carbon (AC) is a unique and versatile carbonaceous adsorbent with a high degree of porosity, well-developed surface area, and specific functional groups that are necessary for the removal of contaminants, making it one of the best candidates for removing pollutants from an aqueous medium. This thesis focuses on utilising oil palm trunk (OPT) as the precursor for the synthesis of AC via chemical activation and semi-carbonisation for the adsorption of tannin, acid blue 25, and sunset yellow in single and binary adsorbate systems. The adsorption behaviours and future application of OPT-derived AC for wastewater remediation are discussed.
