Sejarah artikel:The present study reports the performance of magnetic activated carbon impregnated with Fe 2+ and Fe 3+ on the removal of dye from a simulated wastewater. The magnetic activated carbon (MAC) as a magnetic absorbent was prepared by co-precipitation method and followed by impregnation process. The activated carbon (AC) was supplied from a local commercial activated carbon coconut shell powder. The objective of this study was to investigate the effects of Fe 2+ and Fe 3+ on the quality product of MAC for dye (methylene blue) adsorption. The molar ratios of Fe 2+ and Fe 3+ used during the preparation of the MAC were 1:1; 1:2, and 2:1. The MAC products were characterized by using scanning electron microscope (SEM), energy dispersive X-ray (EDX), and Fourier transform infrared spectroscopy (FT-IR) analysis techniques. The results confirmed that the concentration of magnetic particles (Fe 3 O 4 ) on the MAC surface increased following the impregnation process. However, this results lowering adsorption properties of the MAC adsorbents, which subsequently affected the dye removal performance. The ratio of Fe 2+ :Fe 3+ on the MAC preparation did not significantly change the MAC absorbent on the dye removal efficiency. Additionally, MAC derived from local AC possess a prospect as a sustainable alternative for dye pollutant adsorbent.
