Abstract

The quest to evaluate the efficiency of the electro-degradation process (ECDP) in removing Dinotefuran (DNF), a pesticide, from polluted water has sparked a wave of interest. In this study, we explore the ECDP of Pesticide DNF using both pristine Cu-plate and Cu-foam act as a green electrocatalyst which not involving any hazardous chemicals during the degradation process in an electrolyte solution containing pH 10. When compared with Cu-plate, Cu-foam showed a remarkable seven-fold increase in current density and 3.3-fold boost in electro-degradation efficiency (D.E) (exceeding 95%) for DNF. Also, the pristine Cu foam showed 85.78% chemical oxygen demand (COD) removal efficiency which clearly confirms the completion of degradation of DNF molecule to mineralisation. The ECDP of intermediate products were analysed through spectroscopic, microscopic, and electrochemical techniques. The electron paramagnetic resonance (EPR) study clearly confirms that the powerful synergy between effective hydrolysis and relentless in-situ generated reactive oxygen species (ROS) plays vital role on attacking the DNF backbone. More importantly, we explored the practical applications and toxicity analysis of our findings using earthworm culture media, achieving good degradation of the DNF molecule and highlighting remarkable mineralisation efficiency. This exceptional study underscores extraordinary D. E and rapid response times, greener pathways for significantly reducing DNF levels in agricultural wastewater.
