Synthesis of Green Metaloxide Nanoparticles using Aloe-Barbadensis Leaf Extract (Acid Red 28) for Dye Removal Applications

The present study focuses on the synthesis of stable metal oxide nanoparticles (MO-NPs) using Aloe Vera Barbadensis leaf extracts via a green route approach. MO-NPs were synthesized by interaction Aloe-Barbadensis extract with metaloxide salt and its azodye (Congo red). These NPs then characterized SEM (surface morphology), XRD (Crystallography structure, peaks MO-NPs), UV-Vis (Absorption spectrum) FTIR (presence functional group). images revealed surface morphology nano sized powder while results showed that particle size ranged between 5-30 nm. absorption spectrum are iron copper respectively. data, other hand, indicated hydroxyl (OH) group stretching due to presence alcohols phenolic chemicals in extract. Moreover, effect physical properties such as solution concentration, their PH adsorbent dosage percentage dye degradation was also determined. As per results, removed about 70-80% Congo red at optimum condition reaction factors. dynamics pseudo-second order followed adsorption process MO-NPs.
