Photochemistry of lanthanum series II: Photo-assisted-oxidation reaction of terbium(III) in sodium pyrophosphate solution

Abstract

A Tb(IV) ppt. was formed in photo-assisted oxidation promoted by low pressure Hg lamp (2537 ? in the system: Tb(ClO4)3-Na4P2O7-(NH4)2S2O8-HClO4. The order of reaction and the effect of various factors upon the ratio of Tb(IV) to total Tb in the ppt. was studied. The composition, moment of magnetism, thermal stability, IR spectrum and the separation factor between Tb and other rare earth elements were determine The absorption spectra and the reduction kinetics of Tb(IV) pyrophosphate in acid solution was also investigated.

Key words: AMMONIUM COMPOUND, SODIUM COMPOUNDS, OXIDATION, INFRARED SPECTROPHOTOMETRY, REACTION KINETICS, THERMAL STABILITY, LANTHANON, PHOTOCHEMISTRY, PERCHLORIC ACID, REDUCTION REACTION
