Procedure
Into a 600 ml glass beaker containing a magnetic stir bar was introduced 500 ml of high purity (HP) water. A 1.227 gm quantity of L-leucine was dissolved in this volume. A 5.0 gm quantity of Ce(NO3)3·6(H2O) was added, thereby forming a molar ratio of L-leucine to cerium ion of 0.8. Then a 10 ml solution containing 1.2 gm of 50% H2O2 (1.5 molar ratio of H2O2 to cerium ion) was added slowly to the cerium and leucine solution mixture. The pH was further adjusted to about 2.1 by the addition of 1N HNO3. The reaction product was then heated to 40° C. for 1 hour. The product dispersion was a clear yellow liquid that displayed a high degree of Tyndall scattering when illuminated with a low intensity LASER beam, indicating it contained well-dispersed colloidal particles. Particle size analysis by dynamic light scattering indicated a hydrodynamic diameter of 57.2 nm with a polydispersity of 0.179.
