The detailed potentiometric investigations have been carried out on the system UO₂-oxalic acid-malonic acid-aminodiacetic acid. The formation constants and free energies of formation for all the possible binary, ternary and quaternary complexes formed, have been evaluated. 1 : 1 : 1 : 1 quaternary complexes have been found to be more stable than 1 : 1 : 1 ternary or 1 : 1 binary complexes.
