Procedure

Into a 600 ml glass beaker containing a magnetic stir bar was introduced 500 ml of high purity (HP) water. A 1.429 gm quantity of L-histidine was dissolved in this volume and the solution was heated to about 40° C., forming an alkaline solution. A 10.0 gm quantity of Ce(NO3)3·6(H2O) was added, about pH 6. The molar ratio of L-histidine to cerium ion was 0.4. Then a 10 ml solution containing 1.20 gm of 50% H2O2 (0.75 molar ratio of H2O2 to cerium ion) was added slowly to the cerium and histidine solution mixture. The pH was further adjusted to about 2.1 by the addition of 1N HNO3, thereby forming a clear brown suspension. 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 2.1 mS/cm and a pH of 3.2.
