This study developed and optimized nanocomposites combining biochar and graphitic carbon nitride for photocatalytic degradation of 2,4-dichlorophenoxyacetic acid (2,4-D), a common herbicide contaminant in soil. Using central composite design for optimization, researchers enhanced the photocatalytic efficiency of the nanocomposite material to break down this persistent organic pollutant under light exposure. The optimized composite showed improved performance compared to individual components, demonstrating a promising approach for soil remediation.


This research offers a potential solution for removing persistent herbicide residues from contaminated agricultural soils, which pose risks to ecosystems and human health through groundwater contamination and food chain accumulation. The use of biochar-based materials also presents an environmentally sustainable remediation approach that could be scaled for practical agricultural applications.
