Abstract

The complex formation of azo dyes with CuII-, CoII- or NiII-ions can be carried out as a titration, preferably with CuII and voltametric endpoint indication. It is also possible to determine the above ions with a suitable azo dye. Further analytical possibilities, e.g. the determination of CrIII, are outlined.
