Overview

Randomized trial demonstrates effective removal of phenolic pollutants in water using MnO2 nanoparticles, indicating strong environmental benefits.

Key Points

  • This research aims to optimize the synthesis of MnO2 nanoparticles for enhanced pollutant removal efficiency.
  • Optimized synthesis of MnO2 nanoparticles using response surface methodology based on a central composite design.
  • Characterization of nanoparticles included surface charge, size, and structural analysis.
  • Kinetic and thermodynamic studies assessed adsorption characteristics and effectiveness in removing phenolic pollutants.
  • MnO2 nanoparticles achieved 98.47% removal of 4-Chlorophenol and 97.61% removal of Bisphenol A.
  • Adsorption followed a pseudo-second-order model, indicating chemisorption was involved.
  • The synthesized NPs maintained over 90% removal efficiency after five reuse cycles, demonstrating great stability.
