Аннотация:Optimal conditions have been found for the synthesis of a gadolinium 3,5,5-trimethylhexanoate
complex for creation of stable Gd-loaded scintillators. Procedures for the preparation of gadolinium concentrates containing 10–20 g/L Gd in a linear alkylbenzene have been developed, and their stability has been studied. The structure of gadolinium complexes deposited from the concentrates prepared by extraction has been determined.
