Downloads
In this article, the electrochemical properties of the reagent 2,4-dinitrose-1-hydroxy-5-aminonaphthalene-6,8-disulfonic acid were studied by cyclic voltammetry and chronoamperometry, and an electrochemical method for the determination of thorium (IV) ions was developed. The influence of various background electrolytes and voltage on the determination of thorium (IV) ions was studied. The optimal universal buffer with a pH of 2.82 and a voltage of 1.0 V. The half-wave potential of a complex compound of thorium (IV) ions with 2,4-dinitrose-1-hydroxy-5-aminonaphthalene-6,8-disulfonic acid, equal to 0.42 V., was determined by cyclic voltammetry.
