Electrochemical behavior of copper in solution of potassium chloride under polarization with industrial alternating current is investigated. It is shown, that at polarization of copper-titanium electrode pair by an alternating current with frequency of 50 Hz in the solution of potassium iodide the copper electrode is dissolved, forming compound of copper (I) iodide. It is also shown, that current efficiency of formation of copper (I) iodide is influenced by (i) the density of alternating current, (ii) concentration of potassium iodide and hydrochloric acid in solution. On the basis of the research the optimum conditions of obtaining of copper (I) iodide have been determined. At the optimum conditions the current efficiency of formation of copper (I) iodide was more than 100.0%. The advantages of the electrochemical method are the economical efficiency, simplicity of process, purity of the obtained product, electrolysis at room temperature, improvement of the working conditions.
