The electrochem. oxidn. of phenol in the presence of NaCl for wastewater treatment was studied at Ti/SnO2 and Ti/IrO2 anodes. The presence of NaCl catalyzes the anodic oxidn. of phenol only at Ti/IrO2 anodes due to the participation of electrogenerated ClO- in the oxidn. Anal. of the oxidn. products showed that initially organochlorinated compds. are formed in the electrolyte which are further oxidized to volatile orgs. (CHCl3). [on SciFinder (R)]
