Development of a new method for obtaining copper (I) iodide

Abstract

A new method is proposed for producing copper (I) iodide based on the interaction of iodine and active atomic
copper formed during the reduction of copper (II) ions by titanium (III) sulfate. Previously, electrochemical dissolution of
metallic titanium was carried out under the action of alternating current and trivalent titanium sulfate was obtained. It is
shown that the application of this compound as a reducing agent from copper sulfate solutions leads to the formation of active
elemental copper in the atomic state. During the process the solution was discolored as copper (II) ions were reduced to a
colorless atomic state and titanium (III) ions having a purple color oxidized to a colorless tetravalent state. After that, the
reaction of the interaction of the formed copper with the iodine solution was carried out and the formation of copper (I) iodide
was observed. The obtained compound was identified as copper (I) iodide by x-ray fluorescence, x-ray phase and chemical
analysis methods. The comparison of the developed method with other methods of obtaining copper (I) iodide is carried out.
