Garcia Sanchez, F. published the artcileCoupled redox and complex formation processes as a kinetic fluorometric method for the determination of cobalt, Recommanded Product: 2-((2-(Pyridin-2-yl)hydrazono)methyl)pyridine, the publication is Fresenius’ Zeitschrift fuer Analytische Chemie (1983), 315(6), 491-5, database is CAplus.
A sensitive and relatively interference-free method for the kinetic determination of Co is described. The method is based on the slow oxidation of 2-pyridinealdehyde 2-pyridylhydrazone (PAPH) by BrO3– to a fluorescent product. Complexation of PAPH with Co causes a decrease in the rate of oxidation, which is related to the concentration of Co and also to the stability constant of the complex. The influence of reaction variables and the effect of foreign ions are discussed. Co 20-150 ng mL-1 can be determined with a relative standard deviation of 4%. The absorption of the 1:2 Co PAPH complex was measured at 440 nm.
