Abstract
The coordination properties of alizarin green series dyes with uranyl ions were studied in the presence of cationoid surfactants (cetylpyridinium bromide, carbethoxypentadecyltrimethylammonium bromide). Ternary complexes of the composition UO2L2S2, UO2L2S4, UO2L2S6, and UO2L3S9, where L is dye and S is surfactant, are formed in weakly acid solutions. The formation constants of the complexes were established and a procedure was worked out for the direct photometric determination of uranium.
