Özet
Due to the increased demand for food production worldwide, several pesticides are employed in agriculture to harvest the boosted production with protected quality. Carbofuran is the most toxic carbamate pesticide which was extensively utilized in agriculture for the eradication of pests. It poses significant risks to human health making the swift and accurate detection of carbofuran residue in environment a critical parameter. Here we showcase the electrocatalytic capacity of unique structured carbon nanotubes as fiber which modified with bimetallic nanoparticles (NiCo2O4) and utilized as electrochemical sensor with enhanced detection capacity of carbofuran. A flexible microelectrode has been assembled via a simple and low-cost electrodeposited approach with boosted performance in terms of sensitivity, limit of detection quantification and the linear range. A thoroughly physical, computational and electrochemical characterizations have been done to assess the fabricated material, analyte chemistry and the analysis capacity, respectively. The modified electrode demonstrated a higher sensitivity of 3.51 mAcm−2μM−1 detection limit of 0.05 μM and a linear range of 0.1–12 μM, providing a reliable means of quantifying pesticide. The reported flexible and microelectrode-based sensors could lead this idea to design a portable cost-effective device for the domestic use with reliable performance.
