Abstract
Lutetium(III) forms an association compound with a new synthetic reage nt, bi(1'-phenyl-3'-methyl-5'-pyrazolone-4')hexandione (BPMPHD), and c etyltrimethylammonium bromide (CTMAB). The compound enhances the natur al fluorescence of BPMPHD remarkably, upon which a new fluorescence me thod was developed for determining lutetium in rare earth (RE) samples . The determination range was 1.80 x 10(-7)-8.8 x 10(-6) g/ml. The det ermination limit was 29 ng/ml. The composition of the ion associate wa s [Lu(BPMPHD)(2)](-)CTMAB(+).
