| Abstract: | The fluorescence system of the Eu3+ (or/and Sm3+)-2-benzoyl-indane-1,3-dione(BID)-cetyltrimethylammonium bromide (CTMAB) was investigated at excitation wavelengths of 350
nm, and emission wavelengths at 612 nm for europium and 565, 606 and 650 nm for samarium, respectively. The system was used
for the determination of Eu and Sm in rare earth oxides and of BID in water. Europium or/and samarium could be determined
in the range of 1.0 × 10–9–1.0 × 10–5 mol/L and 2.0 × 10–8–5.0 × 10–5 mol/L, respectively; 1.0 × 10–6–2.0 × 10–5 mol/L of BID could also be determined.
