Abstract
A sensitive and highly selective procedure for the spectrophotometric determination of palladium(II) is described. The method is based on th e formation of ternary ion-association complex, Pd-I--rhodamine 6G, in a citrate buffered medium. The colour system absorbs maximally at 575 nm with molar absorptivity of 8.2 x 10(4) l mol(-1) cm(-1) and obeys Beer's law in the range 1-10 mu g. The method has been applied success fully to the determination of palladium(II) in synthetic mixtures and in standard palladium activated charcoal.
