The kinetics and mechanism of redox reaction of U3+ ions with trichloroacetic acid in the medium of perchloric acid were studied. The form of the dependence of the rate constant on the concentration of H3O+ ions suggests that the U3+ion reacts in the first elementary step with the CCL3.COO- anion under formation of an intermediary radical which reacts rapidly in the second step.The results of kinetic measurements of all three chloro substituted acetic acids are compared. A detailed study of the influence of binary mixtures on kinetic parameters of the studied reaction (especially of water-tert-butanol mixtures) shows that the reduction of chloroacetic acids with U3+ ions proceeds by the outer sphere mechanism of the electron transfer.
