Zusammenfassung:The synthesis of MIL-100(Fe)@Fe 3 O 4 composite modified by CTAB has been reported in this study. This research begins with synthesis of magnetite (Fe 3 O 4 ), using an iron precursor from zircon mining magnetic waste. The MIL-100(Fe)@Fe 3 O 4 was composited with CTAB using a room-temperature in situ synthesis method. The MIL-100(Fe)@Fe 3 O 4 -CTAB composite obtained was then characterized using Fourier Transform Infrared spectroscopy and X-ray diffraction. The synthesized MIL-100(Fe)@Fe 3 O 4 -CTAB was then used to adsorb naphthol dye from the aqueous phase. The maximum naphthol removal was obtained at a concentration of CTAB of 0.4 M and pH of 6. The adsorption kinetics showed that the adsorption followed a pseudo second-order kinetics model, with the rate constant values for MIL-100(Fe)@Fe 3 O 4 -CTAB being 1,712 x 10-2 g/mg.menit, respectively. The results also showed that the adsorption isotherm of MIL-100(Fe)@Fe 3 O 4 -CTAB follows the Langmuir isotherm for adsorption capacities of 63,036 mg/g, respectively. The results indicate that naphthol dye can be effectively removed from the aqueous phase by using the iron content in the magnetic waste from zircon mining, which was used as a precursor for the manufacture of MIL-100(Fe)@Fe 3 O 4 -CTAB composite.
