Study on the Preparation Method of Lanthanum Citrate

Rare Earth technology workers have long been committed to using rare earth citrate in PVC heat stabilizers and rubber additives, and have achieved many satisfactory results. Rare earth citrate can also achieve good results in animal experiments. In the experiment, rare earth citrate was added to animal feed to promote the digestion and absorption of nutrients, thereby promoting animal growth and reproduction. At the same time, the application of rare earth citrate in the medical field has been developing rapidly in recent years. It has a significant effect in anti-cancer and inhibiting tumor cells.

Lanthanum is the most active element among rare earth elements. The lanthanum citrate product formed by it and citric acid also has significant chemically active properties, such as better water solubility and better activation performance, which can be better used. Used in animal feed, plastic and rubber additives, and medical experimental research.

In this study, lanthanum chloride was used as raw material to prepare lanthanum citrate products with crystal structure, high REO content, stable crystal water, easy filtration and good fluidity. The appropriate molar ratio of citric acid to lanthanum chloride, lanthanum chloride concentration, reaction temperature, system pH, aging time and seed addition amount were selected through experiments to prepare crystalline lanthanum citrate LaC₆H₅O₇·3H₂O.
