The process of the interaction of benzene with sodium hypochlorite in a model environment under the action of ultrasonic radiation of different power and under the metered supply of an oxidant solution was investigated. The course of the process was evaluated by the change in the value of the redox potential of the medium over time. By the method of spectrophotometric analysis, it was established that as a result of interaction with sodium hypochlorite in cavitation fields, almost complete mineralization of benzene occurs. It is shown that the oxidative destruction of benzene mainly occurs due to the products of sonolysis of water.
