Area of Science:

• Materials Science
• Electrochemistry
• Environmental Science

Background:

• Bisphenol A (BPA) is an endocrine-disrupting chemical found in water.
• Developing sensitive and selective sensors for BPA detection is crucial for environmental monitoring.

Purpose of the Study:

• To synthesize and characterize a novel ILs-LDH material.
• To develop an electrochemical sensor based on ILs-LDH for sensitive BPA determination.

Main Methods:

• Coprecipitation method for ILs-LDH synthesis.
• Fabrication of ILs-LDH modified glass carbon electrode (GCE).
• Electrochemical characterization and optimization using differential pulse voltammetry.

Main Results:

• ILs-LDH exhibited a layered, disk-like morphology.
• The ILs-LDH/GCE sensor showed enhanced electro-oxidation of BPA.
• Achieved a wide linear range (0.02–3μM) and low detection limit (4.6nM) for BPA.
• Demonstrated good reproducibility, stability, and high sensitivity.

Conclusions:

• The developed ILs-LDH/GCE sensor is a promising tool for accurate BPA detection in environmental water samples.
• The sensor offers a sensitive, stable, and reproducible method for bisphenol A determination.
