| Abstract Scope |
This study introduces a cost-effective, eco-friendly method for synthesizing zinc oxide nanoparticles (ZnONPs) using plantain peel extract (PPE). Characterization techniques revealed that the ZnONPs exhibit a hexagonal wurtzite crystal structure with a predominant zincite phase. X-ray diffraction confirmed their crystalline nature, while Dynamic Light Scattering (DLS) showed an average particle size of 75.35 nm and a polydispersity index (PDI) of 0.45. Fourier Transform Infrared Spectroscopy (FTIR) identified key functional groups: OH, aromatic, and carboxylate. The biosynthesized ZnONPs were applied to industrial paint effluent treatment using Response Surface Methodology (RSM), which determined optimal conditions of pH 6.94, contact time of 74.79 minutes, and adsorbent dosage of 3.16 g/L, achieving a predicted contaminant removal efficiency of 40.90%. The study highlights the potential of plantain peel extract for green synthesis of ZnONPs, offering effective contaminant removal from industrial effluents. |
