Solid-phase-fluorescence intensity of clay–fulvic acid complexes: differences based on amount of fulvic acid adsorbed and examination of correction by using the Kubelka–Munk function

Key Points

• Fluorescence intensity varies significantly based on the amount of fulvic acid adsorbed, highlighting its role in complex formation.
• The study finds that correction using the Kubelka-Munk function provides a more accurate measure of fluorescence intensity.
• Analysis focused on solid-phase-fluorescence measurements to understand interactions between clay and fulvic acid in environmental contexts.
• Understanding these fluorescence properties may have implications for soil chemistry and pollutant interactions.
