Abstract
Dehydracetic acid is proposed as a sensitive reagent for the luminesce nce determination of terbium in lanthanide oxides with a detection lim it of 1 x 10(-5)% (in La2O3). The optimum luminescence conditions have been found, the solvent effects have been studied, and the structure of the resulting chalet is suggested. It is shown that terbium can be determined in the presence of luminescence-quenching elements, and the threshold concentrations of these elements have been determined.
