Özet
Mesotrione, a triketone herbicide, disrupts 4-hydroxyphenylpyruvate dioxygenase (HPPD), leading to chlorophyll bleaching and weed death. However, its persistence in soil and water poses environmental and health risks, contaminating water sources and affecting aquatic life. In the current study, the electrocatalytic performance of as-synthesized nickel oxide-modified carbon nanotubes wrapped via graphene oxide sheets is designed to improve MST detection. A flexible microelectrode based on GO/NiO/CNTs fabricated via a simple, drop casting method and effectively utilized with enhanced performance by providing an efficient platform for pesticide detection in terms of sensitivity, selectivity, limit of detection, and quantification. The modified electrode demonstrated a higher sensitivity of 72 μAmM−1, detection limit of 0.08 mM, quantification limit as 0.80 mM and a linear range of 0.03 mM to 0.83 mM, providing a reliable means of quantifying pesticide (MST). Reported nanohybrid offers a promising pathway for effective environmental monitoring and pollution management using efficient, durable, and cost-effective pesticide detection materials.
