A method for the determination of Ag and Cd at ppb levels in gecchmic:el refernce samples by flameless atomic absorption spectrometry after separati..n with an anion-exchange resin was described The samples are digested with aqua regia. The resultant solutions of O.6N hydrochloric acid were passed through a column of 717 anion exchange resin, and eluted quantitatively with 30 ml 1.5N nitric acid. The amounts of Ag and Cd in the eluate were determined by flameless absorption spectrometry.
