摘要: Abstract The equilibrium in solution between the tricarbonate and dicarbonate complexes of uranyl ion has been investigated. It shown that these species are only existing solutions sodium bicarbonate concentration range 0.03 M–0.15 M. also concluded it is not feasible to isolate complex as form UO22+ carbonate media. A spectrophotometric determination third formation constant UO2(CO3)34− gave a value for k3 = 3.01 × 105 solvent extraction method previously applied overall stability UO2(CO3)22− β2(C) 1.67 1016 (t 20°, μ 0.1). absorption spectrum calculated from optical density measurement.
