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.

Determination Of Copper

Abstract A collaborative study was conducted on the 'atomic absorption spectrophotometric method for measuring the concentration of copper in alcoholic products. In this method, the samples are aspirated directly into the burner of the instrument, and the absorhance values are converted to ppm copper by reference to a standard curve. Data show good precision and are comparable to those obtained by the ZDBT method. It is recommended that the atomic absorption method be adopted as official, first action.
