LUMINESCENT METHOD FOR DETERMINATION OF TERBIUM WITH METHYL ETHYL ETHER OF SULFOSALICYLIC ACID Russian patent published in 2021 - IPC G01N21/63

Abstract RU 2747594 C1

FIELD: chemistry.

SUBSTANCE: invention is used for the luminescent determination of terbium. The essence of the invention is that terbium is converted into a luminescent complex compound with an organic reagent (R) – methyl ethyl ether of sulfosalicylic acid. The ratio is Tb:R=1:1 at pH = 7.0±0.1.

EFFECT: invention is aimed at providing ability to determine terbium with high selectivity, accuracy and reproducibility, as well as providing possibility to determine simultaneously Tb, Dy, Sm, Eu in lanthanide oxides.
