The abstract highlights the development of an electroanalytical sensor for the detection of 2-phenylphenol (2-PPL) as a contaminant. The novelty of the experiment lies in the utilization of a 1-D nanostructured WO/CuO nanocomposite integrated with a carbon paste electrode (CPE). The hydrothermal method was used to synthesize the WO NPs, which were then characterized using Scanning electron microscopy (SEM) and Energy-dispersive X-ray spectroscopy (EDS) techniques.

- Chlorinated organic compounds like 4-chlorophenol (4CP) are widely used but can lead to serious health issues and environmental problems when present in low concentrations.
- Research showed that modifying carbon paste electrodes with tungsten oxide (WO) nanorods and reduced graphene oxide (rGO) nanoparticles significantly improves the detection of 4CP, particularly in alkaline conditions.
- The study demonstrates the electrode's effectiveness for sensitive and selective detection of 4CP in real soil and water samples, with limits of detection and quantification at 0.102 nM and 0.3433 nM, respectively.
The electrochemical performance of linuron (LNR) was studied by fabricating the carbon paste electrode (CPE) using multiwalled carbon nanotubes (MWCNTs) along with zinc oxide (ZnO) nanoparticles (MWCNTs/ZnO/CPE). The influence of electro-kinetic specifications involving steady heterogeneous rate, pH, sweep rate, temperature effect, transfer coefficient, accumulation time, activation energy, as well as the total number of protons and electrons participating in electro-oxidation of LNR has been established using voltammetric techniques like cyclic voltammetry (CV) and square wave voltammetry (SWV). These techniques were applied to investigate LNR in real samples such as soil including water samples.
