Abstract
Sorption preconcentration of thallium(I) on polyurethane foam modified with
molybdophosphate was studied. Optimal conditions for the immobilization of
molybdophosphate and the composition of the adsorbed heteropoly complex we
re determined. A procedure was proposed for the sorption preconcentration o
f thallium(I) and its subsequent determination by atomic absorption spectro
metry in nitric acid desorbates with the determination limit 7.5 mu g/500 m
