Reaction Steps

Into a 600 ml glass beaker containing a magnetic stir bar was introduced 500 ml of high purity (HP) water. A 1.101 gm quantity of L-valine 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-valine 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 valine solution mixture. The pH was further adjusted to about 2.5 by the addition of 1N HNO3. The reaction product was then heated to 40° C. for 1 hour. The product suspension was then washed to remove salts by diafiltration, during which about two turnover volumes of HP water were added, and then concentrated to a final ionic conductivity of about 2.37 mS/cm and a pH of 2.5.
