The hydrolytic decomposition of perxenate ions in acidic solutions has been investigated by kinetic fluorimetry. It is shown that perxenate ions are effective quenchers of excited Tb(III) ions. The rate constant for the quenching of excited Tb(III) ions and the bimolecular rate constant for the deactivation of Tb(III) by perxenate ions are determined from the Stern-Volmer equation. The deactivation process is attributed to the oxidation of the excited Tb(III) ions by perxenate ions. The rate constant for the hydrolytic decomposition of perxenate ions is determined.
