Cathodic electrochemical detection of sonochemical radical products
Cathodic electrochemical detection of sonochemical radical products
This paper reports on an electrochemical technique for the detection of oxidizing radical species, produced as the result of cavitation induced by ultrasound. A study of two example reactions is reported: the Weissler reaction and the Fricke reaction. In both cases, redox-active materials trap oxidative radicals. Electrochemical detection within a flow cell system is then used to sense redox-active products of the reactions between a chosen trapping agent and radicals produced within an ultrasonically irradiated aqueous solution. A demonstration of the sensitivity of electrochemical detection of radical products is presented. An equivalent dose of the ultrasonic reactor is reported.

Abstract
This paper reports on an electrochemical technique for the detection of oxidizing radical species, produced as the result of cavitation induced by ultrasound. A study of two example reactions is reported: the Weissler reaction and the Fricke reaction. In both cases, redox-active materials trap oxidative radicals. Electrochemical detection within a flow cell system is then used to sense redox-active products of the reactions between a chosen trapping agent and radicals produced within an ultrasonically irradiated aqueous solution. A demonstration of the sensitivity of electrochemical detection of radical products is presented. An equivalent dose of the ultrasonic reactor is reported.
