Determination of cerium valent state in solution of CeO₂₋x nanoparticles
Determination of different valence forms cerium in solution of CeO₂₋x nanoparticles was performed using spectrophotometric method. Ce(IV) was determined from the reaction of o-tolidine oxidation in sulfuric-acid medium. The total cerium concentration was determined after reducing Ce(IV) by sodium ox...
