Abstract
Terbium extraction with benzene solutions of acetylacetone, bipyridine, and diphenylguanidine and their mixtures from aqueous chloride solutions, in particular, in the presence of tris(hydroxymethyl)aminomethane was studied. On the basis of terbium distribution in extraction systems in combination with IR and luminescence spectroscopy data for the extracts, the complexation of terbium with these ligands was discussed. The composition of the products of the pyrolysis of extracts was studied. It was shown that pyrolysis of saturated extracts can give nano-sized bulk samples and films on a quartz substrate for both terbium oxide and terbium and manganese mixed oxides.
