Dissociation Field Effect Kinetic Study of Aqueous Samarium(III) Complexation by Murexide.

摘要

The rates of formation of the aqueous samarium (III) murexide complex have been measured at 12 and 25 degrees in the absence of inert electrolyte using the dissociation field effect (E jump) relaxation method. Specific rate constants for complex ion formation are consistent with those obtained previously by the temperature jump technique under different ionic strength conditions, and the activation energy for complexation is comparable to that obtained for solvent exchange on an analogous cation, gadolinium, and for complexation in other closely related systems.
