A flow injection spectrofluorimetric method has been developed for the determination of terbium(III) based on solubilizing its ternary complex with pivaloyltrifluoroacetone(PTA) and trioctylphosphine oxide(TOPO) in micellar solution of nona(oxygethylene)dodecyl ether (BL-9EX). Accuracy and reproducibility are good up to 16 ng/ml of terbium(III) and 80 samples per hour can be analyzed. The relative standard deviation was less than 1.0%. No interferences from 20-fold excesses of 11 rare earth ions were observed.
