Effective degradation of carbofuran and organophosphate pesticides via a continuous-flow, visible-light-activated periodate oxidation system using floatable, sodium alginate/water lettuce-derived biochar/hollow glass microspheres

Puntos clave

• The aim is to determine the effectiveness of floatable biochar beads in degrading carbofuran and other pesticides using visible light and periodate activation.
• Utilized floatable sodium alginate/water lettuce-derived biochar/hollow glass microsphere beads for continuous-flow treatment.
• Activated periodate under light irradiation to facilitate degradation.
• Assessed the stability and toxicity of the treatment system.
• Achieved high degradation rates of carbofuran with the system.
• Noted low toxicity of treated wastewater.
• Demonstrated promising techno-economic feasibility for wastewater treatment applications.
