Abstract

The solvent extraction method involving diglycolic acid dicarboxy methyl ether as a competitive ligand to lutetium and Ntrishydroxymethylmethyl2aminoethanesulfonic acid TES as a buffer was used to study the hydrolysis of lutetium in 1 mol⋅dm−3 NaCl ionic strength at 303 K Acid dissociation constants of H2DG and TES were determined and the possible formation of lutetium–TES compounds was investigated It was found that lutetium does not form compounds with TES under the experimental conditions The solvent extraction method using 177Lu as a tracer was applied and the first hydrolysis constant of lutetium was determined by means of the relationship of the equilibrium constant of the complex LuDG+ in the absence and in the presence of hydrolysis The value obtained was log 10 β LuH=−79±03
