The electrode synergistic adsorption of mixed ligand complexes. Part I. Uranium(VI) salicylic acid/TBP system

In the frame of electrochemical studies on the synergistic adsorption of mixed ligand complexes at the mercury surface, a voltammetric method for the determination of uranyl mixed complex with salicylic acid and tri-n-butyl phosphate in aqueous solutions is investigated. The measurements are based on the accumulation of the uranyl-salicylate complex forming a mixed complex with TBP at the mercury drop electrode. The uranyl concentration at the electrode is enhanced manyfold, so in this way its direct determination in natural water systems, from 10−9 mol dm−3 up to 10−7 mol dm−3 UO22+, is possible.
