Description
The electrochemical oxidation of water containing chloride (Cl<sup>-</sup>) ions has emerged as apotential disinfection and oxidation strategy in which the mixed oxidants, such as ozone,chlorine, and •OH, are generated on-site (Kerwick et al., 2005). However, the formation ofharmful disinfection byproducts such as chlorate (ClO<sub>3</sub><sup>-</sup>) and perchlorate (ClO<sub>4</sub><sup>-</sup>) represents anundesirable side of this process. This study investigates the characteristic ofchlorate formation in electrochemical processes using Cl<sup>-</sup>. In detail, the effects of the followingparameters on chlorate formation were investigated: the mixed oxidants (O<sub>3</sub>, HOCl/OCl<sup>-</sup>, and •OH), dissolved organic carbon (DOC; 0, 1.5, and 2.2 mg L<sup>-1</sup>), pH values (3.6, 5.5, 7.0, 8.0, and9.0).
