A direct method was developed for the quantitation of catalyst metals in phenol by dissolution in an organic solvent mixture. Both flame atomic absorption spectrometry and ICP emission spectrometry of the organic mixtures proved suitable for the determinations, eliminating the difficulties encountered with conventional sample decomposition techniques. A variety of solvent systems and standard compounds were studied to develop a rapid, simple, sensitive method for the direct determination of Pd and Co in phenol. A comparison of analytical procedures is presented, and the stability of organic matrix standards is discussed.
