Of the group of seven pyridyl, thiazolyl and quinolyl azodyes, 2-(2-pyridylazo)-1-naphthol was found to be the most useful for the extraction concentration of traces of copper, nickel, cobalt, cadmium and zinc in methyl isobutyl ketone and for their final determination by atomic absorption spectrophotometry with an acetylene-air flame or using a graphite atomizer. Atomic absorption spectrophotometry was also found to be useful in the study of extraction equilibria and for finding the optimum extraction conditions for these elements with heterocyclic azodyes.
