SIMULTANEOUS COPRECIPITATION OF PD(II), RH(III) AND AU(III) WITH MN(OH)2 WITHOUT CHELATING AGENT PRIOR TO FLAME ATOMIC ABSORPTION SPECTROMETRY DETERMINATION

A separation-preconcentration procedure was developed for determination of trace amounts of palladium, rhodium and gold in dust and water samples by flame atomic absorption spectrometry after simultaneous coprecipitation by Mn(OH)2 without chelating agent. The precipitate could be easily dissolved w...
