Objective

Adopting the protocol for the synthesis of [CeK(H2O)12][Ce(H2O)6]2[(H2O)4CeBW11O39H]2·20H2O, a synthesis was performed using Ce(SO4)2 rather than Ce(NO3)3.

Protocol

  • Dissolved 0.6671g (~2 mmol) Ce(SO4)2 in 20 mL of DI water.
  • Dissolved 1.6112g (~0.5 mmol) K8[BW11O39H]·13H2O in 40 mL of DI water.
  • Added the second solution to the first solution.
  • Verified pH was ~3.5
  • Refluxed solution with stirring for 2 hours at 80°C.
  • The resulting solution was saved for filtration on Thursday

Notes

  • Cerium sulfate did not seem to go into solution.
  • When solutions were mixed, there appeared to be some settling of precipitate.
  • Reflux solution was yellow and solution was not clear (possibly as a result of precipitates agitated by the stir bar.

FTIR

  • FTIR was performed on:
    • Europium Acetate
    • Europium Acetate Product
    • Lanthanum Chloride
    • Lanthanum Chloride Product
