Solar-driven degradation of HEDP and simultaneous phosphorus recovery from electroplating wastewater via a Cu (III)-mediated biochar electro-Fenton system

Key Points

• Phosphorus recovery from wastewater reached up to 80% efficiency using the Cu (III)-mediated electro-Fenton system.
• The biochar material significantly enhanced the solar-driven degradation of HEDP, leading to effective pollutant breakdown.
• Assessment using an electro-Fenton system showed promise in reducing hazardous compounds via oxidative reactions.
• Highlights the potential for environmentally friendly wastewater treatment methods, indicating further studies may improve scalability.
