✦ Synopsis

A procedure is described in which gold and palladium are quantitatively recovered from anode slimes using a short column .with Amberlite XAD-7 resin, followed by their spectrophotometric determination as bromo complexes. Their separation was carried out in 0.4 M NaBr, 0.01 M K!XN and 0.05 M HNO, media. The gold and palladium concentrations in the samples were found to be 996 f 5 and 3.7 f 0.2 pg g-', respectively. The relative standard deviation of the combined dissolution, separation and determination method was ca. 5% (n = 7).
