【 摘 要 】

Ultrasonic cavitation effects can generate hydroxyl radicals and high energy, which is widely applied in the field of oxidation currently. Ultrasound-enhanced electrochemical is used to prepare Caro's acid, which improves the generate rate of Caro's acid. In this article, the influences of ultrasonic frequency and ultrasonic power on the electrolysis voltage, electrolyte temperature, electrolyte concentration and the concentration of additive in the process of electrochemical preparation of Caro's acid was studied. And the optimal production conditions were determined. The research results showed that ultrasonic can significantly improve the production of Caro's acid and the product can increase by about 20 g/L under the best condition.
