Unravelling the potential of bismuth ferrite nanoparticles for electrochemical pesticide detection
Monocrotophos (MCP)—a toxic organophosphorus (OP) insecticide—has been widely used in the agricultural field to protect crops from weeds, vectors, insects, etc. Among the different OP pesticides—methyl parathion, dichlofenthion, paraoxon, etc.—monocrotophos is the one which is frequently used by farmers because of its high insecticidal prevention activity. Due to its excellent solubility in water, the residues of MCP have a high chance of entering into the human food cycle which sequentially causes acute poisoning and various health issues. To address it, an effective detection system should be implemented that has the capability of detecting MCP at very low concentrations. Herein, bismuth ferrite particles with varied morphology and surface properties are synthesized using sol–gel and hydrothermal methods, and their sensing properties are effectively compared. Structural, morphological, and surface area measurements are carried out by TG/DTA, XRD, FTIR, HRSEM, and BET, respectively. Consequently, fluorine-doped tin oxide (FTO)-modified bismuth ferrite (BFO) electrodes were used for electrochemical detection of monocrotophos. Relatively, bismuth ferrite xerogel powders exhibit good stability for up to 3 weeks with a limit of detection (LOD) of 0.638 µM. From the laboratory study, it can be understood that the synthesis procedure plays a crucial role in the electrochemical detection of pesticides.
期刊介绍：
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
