Used in water treatment processes to remove heavy metals and impurities through co-precipitation and adsorption mechanisms. The combination enhances the formation of insoluble metal complexes, improving purification efficiency. Applied in industrial wastewater treatment to meet environmental discharge standards. Also utilized in soil remediation to immobilize contaminants like lead and cadmium, reducing their bioavailability. In agriculture, helps in controlling nutrient release in fertilizers by forming less soluble phosphate compounds, thus preventing leaching and enhancing nutrient uptake. Plays a role in corrosion inhibition in cooling systems by forming protective layers on metal surfaces.
