Biogenic synthesis of NiO nanoparticles using Ficus religiosa and their application to sequestrate anionic dye

Puntos clave

• The aim is to synthesize NiO nanoparticles using Ficus religiosa and evaluate their effectiveness in removing anionic dye from contaminated water.
• Synthesis of NiO nanoparticles from Ficus religiosa extract.
• Testing the nanoparticles' ability to remove anionic dye from water samples.
• Evaluation of removal efficiency under different conditions.
• NiO nanoparticles exhibited a high removal rate of anionic dye, achieving over 90% sequestration in optimal conditions.
• The binding affinity of the nanoparticles to the dye was found to be significant, with statistical relevance (p<0.05).
• The study suggests potential for using biogenic synthesized nanoparticles in water purification.
