Characterization of Al2O3 Nanoparticles from AlCl3 with Syzygium aromaticum L. Leaf Solid Waste Extracts as Bioreductor Chemical Engineering, Universitas Pembangunan Nasional Veteran Yogyakarta- Environtmental Engineering Universitas Pembangunan Nasional Veteran Yogyakarta Abstract This study aims to present the findings from characterizing the green synthesis of Al2O3 nanoparticles using Syzygium aromaticum L leaf solid waste extract as a bioreductor. The functional groups of the Al2O3 nanoparticles were examined through Fourier transform infrared (FTIR) spectroscopy. FTIR analysis showed that Al2O3 is characterized by (AlO)-OH bonds at 539,5 cm-1 and Al-O Vibration at 762 cm-1. Other bonds, such as O-H, indicating the presence of intramolecular hydrogen bonds, were observed at wavelength 3395,43 cm-1. Additionally, our results showed that the pseudo-first-order model for methylene blue adsorption offered the best fit of the experimental data.
