Résumé

In this study, the presence of Cu(II) ions was found for the first time to severely inhibit +-dimethyl phthalate (DMP) degradation by ozone due to the formation of the stable complex Cu(II)-DMP. However, 100% DMP removal was rapidly reached when ethylenediamine tetraacetic acid (EDTA) was added with a Cu(II)/EDTA molar ratio of 3:1. Subsequent studies indicated that Cu(II)-DMP is sequestrated by EDTA, then DMP was degraded and Cu(II) was removed by precipitation. The freshly formed Cu-EDTA
