3D Fluorescence Spectroscopy: An Innovative Tool for Water Quality Management

Disinfection byproducts, explosives residues, pesticides, fertilizers, and heavy metals in tap water are invisible health threats. Studies show that 79% of people nationwide face the issue of drinking polluted water, and 80% of diseases are water-related. However, simple boiling cannot remove heavy metals, pesticides, and other toxins from water. Therefore, ensuring safe drinking water from the source has become a top priority.

Water Quality Fingerprint Pollution Tracing Technology is a breakthrough in water environment monitoring. It introduces fingerprint recognition from criminal investigation into the water environment field, effectively solving the problems of difficult and slow water pollution tracing.

Technical Principle and Monitoring Process

• 3D Fluorescence Spectrum：A spectral graph with emission wavelength on the horizontal axis, excitation wavelength on the vertical axis, and fluorescence intensity as contour lines.

• Water Quality Fluorescence Fingerprint: A three-dimensional fluorescence spectrum representing the composition of pollutants in a water sample.

• Pollution Tracing: The process of detecting the water sample's fluorescence fingerprint, comparing it with known pollution sources, determining the path, verifying results, and identifying the pollution source.
