A Dual-Function Gold–Zinc Ferrite Nanocomposite Sensor for Colorimetric Detection of Phosphates in Environmental Water

Key Points

• The aim is to develop a sensor that can simultaneously detect and quantify phosphate levels in environmental water to address eutrophication issues.
• Developed a gold-zinc ferrite nanocomposite sensor
• Conducted colorimetric tests for detecting phosphates
• Analyzed sensor performance in simulated water samples
• The sensor effectively detects phosphates at low concentrations
• Demonstrated a clear color change in response to phosphate presence
• Showed potential for use in environmental monitoring applications
