Grases, F. published the artcileIndirect spectrofluorometric kinetic determination of palladium and nickel based on the oxidation of 2,2′-dipyridylketone hydrazone and dipyridylglyoxal hydrazone, Recommanded Product: 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine, the publication is Analytica Chimica Acta (1984), 359-64, database is CAplus.
Kinetic methods for Pd (0.1-0.8 mg L-1) and Ni (0.1-0.7 mg L-1) are based, resp., on the uncatalyzed bromate oxidation of 2,2′-dipyridylketone hydrazone (DPKH) in acidic media and of dipyridylglyoxal hydrazone (DPDKH) in basic media, to yield fluorescent products. Complexation of DPKH and DPDKH by Pd(II) and Ni(II), resp., causes a decrease in ligand concentration and thus in reaction rate, which can be related to the concentration of metal. The method for Pd is relatively free from interferences.
