Abstract: | Summary The species, UO2H3L–, UO2H2L2–, UO2HL3–, UO2L4–, UO2(OH)L5– and UO2(OH)2L6– are found in the equilibria between uranyl ions and 3,3-bisN,N-di(carboxymethyl)-aminomethyl]-o-cresolsulphonphthalein (H6L; xylenol orange; dcac) in aqueous solution. The equilibria have been studied by the potentiometric method at 25° and at an ionic strength of 0.1M (KNO3). New algebraic equations have been employed to evaluate the equilibrium constants. |
