“…The broad-spectrum pesticide shows multifunctional properties such as seed disinfectants, algicides, and fungicides and thus can be applied for residential and commercial outdoor use. 19 DCN has been classified as a hazardous substance by the US EPA and OSHA (Occupational Safety and Health Administration) agencies; 25 thus, trace-level assessment of the DCN is also vital.…”

The utilization of doped WO 3 nanostructures as an active component in electrochemical sensors is a promising strategy for delivering highly sensitive and stable detection schemes. In this work, a nanostructured WO 3 possessing a mixture of nanoparticle and one-dimensional (1-D) architecture, doped with Ta, was synthesized via hydrothermal reaction for electrochemical sensor application. Substituting Ta in W lattice positions yields polymorphic crystals with n-type characteristics. An optimized Ta content of 2.02 at. % in WO 3 was utilized for detailed electrochemical analysis of diuron (DIU) and dichlone (DCN). An electrochemical sensor was fabricated by packing the mechanically intercalated Ta-WO 3 /carbon matrix into a Teflon tube. The developed Ta-WO 3 /CPE could be employed for the selective and sensitive electrocatalytic determination of DIU and DCN in the presence of the cationic surfactant, viz., CTAB. The CTAB-mediated Ta-WO 3 /CPE exhibited good linearity with remarkable detection limits of 5.2 and 0.4 nM for DIU and DCN, respectively. The sensor displayed good sensitivity of 4.8 (for DIU) and 38.7 μA•μM −1 •cm −2 (for DCN) with selectivity, demonstrating real-time efficiency for DIU and DCN determination in spiked soil and water samples with satisfactory results.
