Overview

Randomized trial demonstrates efficient methylene blue degradation in wastewater, suggesting potential for improved dye treatment.

Key Points

  • This study aims to enhance peroxymonosulfate activation for dye degradation using a modified hydrochar catalyst.
  • Developed a CoFe2O4-modified hydrochar catalyst from wheat straw for PMS activation.
  • Optimized reaction conditions for maximum methylene blue removal efficiency.
  • Performed radical quenching experiments and LC–MS analysis to investigate degradation pathways.
  • Achieved a maximum methylene blue removal efficiency of 99.8%.
  • Maintained an MB removal efficiency of 68.8% and a COD removal efficiency of 60.65% after five reuse cycles.
  • Identified SO4·− as the dominant radical in the degradation process.
