ABSTRACT
An efficient adsorbent was derived from Sargassum boveanum macroalgae (BCM) through a thermal pyrolysis process. It was characterized and investigated for the removal of 2,4,6–Trichlorophenol (TCP) from the aqueous solution. The effects of adsorbent mass, adsorbate concentration, and contact time were examined. The maximum removal efficiency and adsorption capacity were 100% and 175 mg g−1, respectively. The adsorption fitted Freundlich model and followed pseudo-second order kinetics. It was also found that the adsorption process was spontaneous, endothermic, and thermodynamically favorable. This study indicated that BCM adsorbent can remove 60% of TCP from the high saline seawater and it is reusable for three times.
