摘要：

A method for the synthesis of chromeayurol-s (CA-S) chelate forming resin and the determination of traces of gold and palladium in geological samples is presented. Experiments have shown that gold and palladium in solution are enriched on chromeayurol-s chelate forming resin column in pH 1 hydrochloric acid without adsorpting other base metal irons, and are eluted with 3% acidic thiourea. The eluate is determined directly by flame atomic absorption spectrometry. Operating parameters are studied in detail. The relative standard deviations (n = 6) of gold and palladium are 8.50 and 7.24%. (C) 1996 Academic Press, Inc.
