Abstract

The spectrophotometric determination of palladium(II) with 5-phenylazo-8-aminoquinoline (PAQ) is described. The method involves the formation of a Pd-APQ complex in dilute HCl solutions and the conversion of this complex into Pd(PAQ)2 by addition of NaOH. This latter complex is extracted into methyl isobutyl ketone and the absorbance is measured at 620 nm. The molar absorptivity is 7.9×104l·mole-1·cm-1. The method is applied to the determination of Pd(II) in catalysts. © 1983 Springer-Verlag.
