| Abstract: | The formation constants of neodymium complexes in sulfate solutions have been determined spectrophotometrically at temperatures of 30-250 °C and a pressure of 100 bars. The dominant species in the solution are NdSO4+ and Nd(SO4)2−, with the latter complex being more important at higher temperature. Equilibrium constants were calculated for the following reactions: |
