Abstract

The paper presents the results of investigations on the use of high-frequency ultrasonic cavitation of 1.7 MHz (US), in the Fenton-like iron-persulfate system and in the combined system for destruction Bisphenol A (BPA) in aqueous solutions. The studies revealed that the most effective treatment process involves high-frequency ultrasound in the megahertz range, compared to low-frequency ultrasound, is more energy efficient for sonochemical reactions. The results of this research revealed that the rate of the BPA oxidation reaction increases in the series: . The oxidative system, complete destruction of the target compound is observed, while the mineralization of total organic carbon reaches 30 %
