Özet

Studying electrolysis processes in drinking water disinfection it was found that chlorate and perchlorate can be formed at high extent on several electrode materials. Formation potential differs by orders of magnitude comparing mixed oxide (MIO), Pt and boron doped diamond (BDD) anodes. Highest concentrations were found using the doped diamond electrodes. Extended studies showed that chlorate and perchlorate may be formed also in other processes of so-called Advanced Oxidation. Therefore, the authors propose both components as new inorganic assessment criterions in environmentally-oriented water treatment.
