Abstract
This study focuses on the electrochemical detection of 4-nitrophenol (4-NP) utilizing Ag@Ag2MoO4 microcubes, PANI-Ppy, and their nanohybrid. 4-NP is known for its environmental hazards and high toxicity, making its detection crucial. The synthesis of Ag@Ag2MoO4/PANI-Ppy is employs a microwave technique, followed by electrode fabrication using a drop-casting method. Structural, optical, morphological, and electrochemical characterizations were conducted to evaluate their efficacy for 4-NP detection. The modified electrode demonstrated a limit of detection (LOD) of 72 nM and a limit of quantification (LOQ) of 241.31 nM, with excellent selectivity against various interferences. Real water samples validated the modified electrode's viability, yielding positive recovery values. A comprehensive mechanism for the electrochemical detection of 4-NP is proposed.
期刊介绍:
Electrochimica Acta is an international journal. It is intended for the publication of both original work and reviews in the field of electrochemistry. Electrochemistry should be interpreted to mean any of the research fields covered by the Divisions of the International Society of Electrochemistry listed below, as well as emerging scientific domains covered by ISE New Topics Committee.
