Pyridine-2-carbaldehyde derivative of Girard-P as a fluorimetric reagent for the determination of gallium in aluminium

A fluorimetric method for the determination of Ga, based on the formation of a fluorescent 1:1 chelate with PAHP (the pyridine-2-carbaldehyde derivative of Girard-P), is described. In aqueous solution, the fluorescent species has excitation and emission max. at 388 and 442 nm, respectively, and the...

Summary:A fluorimetric method for the determination of Ga, based on the formation of a fluorescent 1:1 chelate with PAHP (the pyridine-2-carbaldehyde derivative of Girard-P), is described. In aqueous solution, the fluorescent species has excitation and emission max. at 388 and 442 nm, respectively, and the calibration graph is linear over the range 10-500 p.p.b. at p H 3.7. The method has been employed for the determination of Ga in Al. 13 ref.--AA(UK).
