Abstract

ABSTRACT

Phenol adsorption using composite adsorbent Fe₃O₄-activated charcoal coffee grounds has been done. Composite adsorbent Fe₃O₄ -activated charcoal coffee grounds are synthesized from FeSO₄. 7H₂O and FeCl₃. 6H₂O with a ratio of 3: 2 and then compiled with activated coffee charcoal. The composite adsorbent Fe₃O₄-activated coffee charcoal was characterized by Fourier Transform Infared (FTIR) and Scanning Electron Microscopy (SEM) as well as the adsorption test on phenol. The results of the characterization with Fourier Transform Infared (FTIR), peak 1604.77 cm^-1 appeared showing the absorption of C=O which states that coffee grounds have formed carbon. Beside that, Fe₃O₄-activated charcoal composite adsorbent peaks appear at a wavelength of 509.21 cm^-1 which is a Fe-O group showing that Fe₃O₄ nanoparticles have been successfully grafted on the active charcoal structure. The optimum conditions of phenol adsorption using adsorbent composite Fe₃O₄-activated coffee grounds at 30 minutes contact time and pH 5.
