Abstract

This study focuses on synthesizing aluminium oxide nanoparticles using aluminium chloride and investigates their potential for removing cadmium from wastewater. The synthesized nanoparticles were thoroughly characterized to determine their structural and luminescence properties. The results indicate that the nanoparticles possess a crystalline structure and exhibit luminescence behaviour in the visible region. X-ray diffraction analysis confirmed the formation of rhombohedral aluminium oxide nanoparticles. The XRD pattern revealed the (012), (104), (006), (202), (024), (116), and (300) peaks of Al2O3 nanoparticles with crystallite sizes ranging from 46-68 nm. Moreover, UV-Vis spectrophotometer analysis revealed a significant increase in absorption intensity when aluminium oxide nanoparticles were introduced, demonstrating their effectiveness as an adsorbent for cadmium removal from wastewater. Aluminium chloride yielded superior results in synthesizing aluminium oxide nanoparticles.
