OH radical production during electrolysis of water was monitored to show that it could be involved in an indirect oxidation of pollutants in electrochemical wastewater treatment. The OH radical concentration in the electrochemical reactor was measured by using a probe compound, p-chlorobenzoate (pCBA).
