    Abstract:

    The metals ions of wastewater including Cu(Ⅱ),Mn(Ⅱ),Fe(Ⅱ), Fe(Ⅲ) and Al(Ⅲ) were selected as representatives, and the experiments were carried out to assess the effects of metal ions on TNT-removal by O3/H2O2 in the wastewater. The experimental results showed that effects of metal ion on the TNT degradation with O3/H2O2 depend on the metal types and their concentrations in the wastewater. Cu2+ suppresses the degradation. Mn2+with a low concentration enhances the degradation, but suppresses the degradation with high concentration. The effects of Fe2+ and Fe3+ are opposite to that of Mn2+, and they enhance the degradation with low concentration and inhibit it with high concentration. Al3+ has a small potential to improve the degradation. Cu(Ⅱ), Fe(Ⅱ), Fe(Ⅲ) inhibit the TNT-degradation by O3/H2O2 by blocking forming of hydroxyl radicals, and Mn(Ⅱ) does that by shorting the hydroxyl radical age.
