Data confidence 70 medium

How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

\nThe 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.\n
