"Flow Injection Spectrofluorimetric Determination Of Terbium(III) Based On Solubilizing Its Ternary Complex In Micellar Solution"
Anal. Lett. 1986 Volume 19, Issue 19&20 Pages 1907-1916
Aihara, M.;Arai, M.;Tomitsugu, T.

Abstract: The method is based on the solubilization of Tb - pivaloyltrifluoroacetone - trioctylphosphine oxide in a micellar solution of nona(oxyethylene) dodecyl ether. The flow injection system consists of a reciprocating pump with two channels, a 6-way injection valve, a 32 µL flow cell and a coil length of 1 m (0.5 mm i.d.). Fluorescence detection is at 611 nm (excitation at 310 nm) and a flow rate of 1 mL min-1 is used. Calibration graphs are rectilinear from 16 to 160 ng mL-1 and, at the 0.5 µM level, the coefficient of variation was <1%; 80 samples h-1 can be analyzed. A 20-fold excess of other rare-earth ions, except Pr and Gd, had no significant effect on the determination of 76 ng mL-1 of Tb.

"Flow Injection Spectrofluorimetric Determination Of Terbium(III) With Ethylenediamine Bis-(o-hydroxyphenylacetic Acid)"
Fukuoka Joshi Daigaku Kaseigakubu Kiyo 1989 Volume 20, Issue 1 Pages 29-33
Aihara, M.;Kobayakawa, M.;Taketatsu, T.

Abstract: Sample solution (100 µL) containing 0.1 to 10 µM Tb(III) were injected at 40 h-1 into a stream (0.8 mL min-1) of 0.1 mM HCl and mixed with 0.6 mM ethylenediaminebis(o-hydroxyphenylacetic acid) (pH 7.7) in a reaction coil (2 m x 0.5 mm) and the chelate formed was determined fluorimetrically at 545 nm (excitaion at 295 nm). Equimolar amounts of other rare-earth ions did not interfere. The coefficient of variation was 1.2%.
