Procedure
Into a 600 ml glass beaker containing a magnetic stir bar was introduced 500 ml of high purity (HP) water. A 0.993 gm quantity of L-Phenylalanine was dissolved in this volume. A 5.0 gm quantity of Ce(NO3)3·6(H2O) was added, thereby forming a molar ratio of phenylalanine 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 phenylalanine solution mixture, and a pH of about 4.3 was recorded. 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 30.45 nm with a polydispersity of 0.183.
