Spectrophotometric Determination Of Palladium Using Some Halogen Derivatives Of Phenylazo-Chromotropic Acid

A comparative study on the reaction of o-chloro-, m-chloro-, p-chloro-, o, p-dichloro-, p- bromo-, and p-iodo- phenylazochromotropic acid with Pd (II) ions have shown that two 1:2 (metal: ligand) violet water soluble complexes are formed at two different pH values» The p-derivatives were found to be very suitable reagents for the spectrophotometric determination of Pd (II) up to 6.3-8.3 ppm. The application of these dyes as indicators in the spectrophoto¬metric titration of Pd (II) with EDTA and the effect of various cationş and anions on the determination were reported.
