Abstract

The results of oxidising dechlorination in solution CuCl2–TBP–HCl–NaNO2–О2–Н2О in an ultrasonic field kinetics research are presented in the article. Influence of all system components, influence of modulation frequency and time of the ultrasound exposition is studied and quantitatively described. It is shown that in the presence of ultrasound the system redox potential increases by 200 mV, the binuclear copper(II) complex formation constant increases by one order at smaller (approximately by one order) acidity of the solution.
