Separation and Preconcentration of Gold, Silver and Palladium from Some Aluminum and Manganese Salts on Activated Carbon Column

Abstract

A simple method for preconcentration and separation of trace amounts
of gold, silver, palladium in some aluminium and manganese salts was
established by using mini column filled activated carbon prior to their
atomic absorption spectrometric determinations. The dithiophosphoric acid
O,O-diethyl ester complexes of the analyte ions were adsorbed on the
activated carbon column and desorbed with 2M NH₃ in acetone. The effects
of aluminium and manganese ions as interferent were discussed. The
method was successfully applied for the determination of Au, Ag and Pd
contents of some aluminium and manganese salts (recoveries> 95%, relative
standard deviations < 10%).
