Abstract: Calcein blue has a strong fluorescence (excitation at 370 nm, emission at 440 nm) that is sensitively quenched by the presence of trivalent lanthanide ions. The analysis system consists of a reciprocating pump with two channels (one for HCl carrier solution, and another for reagent solution), a 6-way sample injection valve, a 3 m reaction coil, a spectrofluorometer with a 32 mL flow cell, a 1 m back-pressure coil, and polyethylene tube manifold (0.5 mm i.d.). A series of experiments was conducted to find the optimum analysis conditions for the system. A 100 mL of sample solution containing 10^-6 ~ 10^-4 M Sm(III) was injected into the carrier stream under the following optimum analysis conditions: concentration of reagent, 7 x 10^-5 M in tris(hydroxymethyl)[aminomethane buffer solution at pH 8.0; carrier solution, 10^-4 M HCl; flow rate, 1.0 mL min-1; and manifold tube length, 3 m. The relative standard deviation was ≤0.11%. The system can analyze 40 sample solutions per h, and can be applied to all members of the lanthanides with equal sensitivity.

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%.

Abstract: 1-Amino-4-hydroxyanthraquinone is oxidized by Ce(IV), with 5 mM KClO3 as catalyst, and the fluorescent product is determined at 541 nm (excitation at 489 nm). The calibration graph is rectilinear for 30 to 100 µM-Ce. The sampling rate is 45 h-1.
