Color Reaction of 5-(Phenylazo)-8-(4-nitro-1-phenyldiazo)-aminoquinoline with Palladium and Its Application
-
ABSTRACT
Color reaction of 5(phenylazo)8(4nitro1phenyldiazo)aminoquinoline (PANPAQ) with palladium() was studied. In a weak alkaline medium and in presence of OP, Pd() reacts with PANPAQ to form a blue stable complex with nPANPAQnPd()=21. The maximum absorption is
