A kinetic investigation of neodymium sulphate complexation in D2O as a test of the Eigen mechanism
Abstract
Since NdSO4+ formation was slowed by a factor of 2·3 in D2O as compared with H2O while the dissociation was accelerated, the Eigen complexation mechanism predicting cation–solvent exchange as the slow step, cannot be the controlling mechanism in lanthanoid complexation reactions.
