摘要：

A spectrophotometric study of palladium complexation in concentrated nitrate and acid solutions is presented. The water activity of the solutions was fixed to control activity coefficients. The existence of the species PdNO3+, Pd(NO3)(2) and PdOHNO3 has been evidenced and their stability was evaluated. An activity diagram for the predominance of soluble palladium species is presented and the precipitation limit is drawn.
