Cathodic Action of the Uranyl-Malate Complexes at the Dropping Mercury Electrode

Abstract
The uranyl ion in malic acid solution has been investigated by polarography and conductometry. Evidence has been presented for the existence of three kinds of chelate species, , , and . Their structures and electrode reactions at various pH values have been established. In the temperature range from 9.1° to 21.5°C the chelates exist as a dimer. On raising the temperature to 28.5°C the depolymerization takes place completely to form a monomer.
