Abstract
A simple and highly selective procedure for the spectrophotometric det ermination of palladium is described. It is based on the formation of the ternary ion-association complex Pd-SCN--Rhodamine 6G in a citrate buffer medium. The colour system obeys Beer's law in the range from 0 to 10 mu g of palladium present in a final volume of 25 ml (epsilon = 8.8x10(4) l mol(-1) cm(-1)). The method has been successfully applied to the determination of palladium in the palladium activated charcoal (palladium catalyst).
