Description

Effect of sodium tetraphenylborate (NaTPB) and polyether 18-crown-6 on solution stability of SM2+, Tm2+ Nd2+ and Dy2+ in certain solvents has been studied. It is shown that the use of NaTPB for stabilization of Dy2+ and Nd2+ is impossible due to instability of the reagent to oxidation potentials below - 2.3 V. The use of 18-crown-6 permitted to prepare more stable Sm2+ solutions in water and Tm2+ solutions in acetonitrile, than in pure solvents. The values of oxidation rate constants and certain spectroscopic data for bivalent lanthanides in the media studied are presented
