Abstract

Hydrous, amorphous MnO2–TiO2 composites demonstrating high affinity towards strontium and uranium at pH = 7 are obtained by means of template synthesis. The best distribution coefficients, as found using model solutions (K d Sr = 55000 mL/g and K d U = 40000 mL/g) and Chernobyl shelter water (K d Sr = 3800 mL/g), are gained for the samples containing equimolar amounts of manganese dioxide and titania precipitated using K+ as template cation.
