Application Fields of Lanthanum-Cerium Citrate

1.Agricultural Field: Lanthanum-cerium citrate can be used as a new type of fertilizer and plant growth regulator. The rare earth elements lanthanum and cerium can promote plant photosynthesis, enhance the root system's ability to absorb nutrients and water, and regulate the hormone balance in plants, thereby improving crops' stress resistance (such as drought resistance, cold resistance, and pest resistance). As a natural chelating agent, citric acid can protect rare earth ions, improve their stability and bioavailability in the soil, and reduce the risk of them being fixed by the soil and becoming ineffective.

2.Environmental Protection Field: Lanthanum-cerium citrate can be used to treat pollutants in water bodies and soil. Lanthanum and cerium have unique redox properties and surface activity, enabling them to undergo adsorption, complexation, or catalytic reactions with pollutants. In sewage treatment, lanthanum-cerium citrate can act as a flocculant or catalyst to remove heavy metal ions (such as lead, cadmium, mercury) and organic pollutants (such as dyes, pesticide residues) from water. The complexes formed by its combination with pollutants are separated from the water body through precipitation or filtration, achieving the purpose of purifying water quality.

3.Soil Remediation Field, lanthanum-cerium citrate can reduce the bioavailability of heavy metals in the soil, decrease plants' absorption of heavy metals, thereby reducing the content of heavy metals in agricultural products and remediating contaminated soil.

4.Material Science Field: Lanthanum-cerium citrate also has certain applications. It can be used as a precursor for preparing rare earth-doped functional materials, such as ceramics, catalyst carriers, and luminescent materials. In terms of catalytic materials, catalysts prepared from lanthanum-cerium citrate exhibit good catalytic activity and stability in organic synthesis reactions, automobile exhaust purification, industrial waste gas treatment, etc.

5. Luminescent Materials Field, lanthanum-cerium citrate can serve as an auxiliary component, acting synergistically with other rare earth luminescent ions to regulate the luminescent properties of materials, and is used in the manufacture of phosphors, LED lighting devices, etc.
