This study aimed to synthesize nanosized Mg0.2Fe2.8O4/AC/TiO2 composite for removal Pb(II) from water. The crystal structure and functional group of the sample were evaluated using XRD and FTIR spectroscopy. The morphology and band gap energy of the sample were characterized by means of SEM and UV-Vis spectroscopy. Meanwhile, the absorbance performance of the composite for removal Pb(II) was evaluated using AAS characterization. The results of the data analysis in this study showed that the Mg0.2Fe2.8O4/AC/TiO2 composite was successfully synthesized using coprecipitation method. The result of the XRD characterization presented the two phases for Mg0.2Fe2.8O4 and TiO2. The FTIR characterization results showed that the composite had a Fe-O bond at the tetrahedral and octahedral positions that were detected in the wavenumber range of 800-500 cm-1. The SEM image showed that the morphology of composite tended to agglomerate with a particle size distribution of 44.3 nm. The band gap energy resulting from the UV-Vis data analysis was 3.492 eV. Interestingly, the absorption efficiency for removal Pb(II) of the Mg0.2Fe2.8O4/AC/TiO2 composite reached 99.08%-99.90%. © 2024 Author(s).
