Abstract
A spectrophotometric study of palladium complexation in concentrated n itrate and acid solutions is presented. The water activity of the solu tions was fixed to control activity coefficients. The existence of the species PdNO3+, Pd(NO3)(2) and PdOHNO3 has been evidenced and their s tability was evaluated. An activity diagram for the predominance of so luble palladium species is presented and the precipitation limit is dr awn.
