Most of the compounds have physiologically active properties, and their biological properties are often attributed to the heteroatoms contained in their molecules, and most of these heteroatoms also appear in cyclic structures. A Journal, Journal of Cleaner Production called Effective removal of the heavy metal-organic complex Cu-EDTA from water by catalytic persulfate oxidation: Performance and mechanisms, Author is Wang, Qi; Li, Yutong; Liu, Yue; Ren, Jingyu; Zhang, Ying; Qu, Guangzhou; Wang, Tiecheng, which mentions a compound: 12069-69-1, SMILESS is O[Cu]OC(O[Cu]O)=O, Molecular CH2Cu2O5, Formula: CH2Cu2O5.
It is difficult to remove heavy metal-organic complexes from water by chem. precipitation because of the strong complexation ability between heavy metal ions and organics In this study, the removal of the Cu-EDTA (Cu-EDTA) complex using autocatalytic persulfate (PS) oxidation was investigated. The Cu-EDTA removal efficiency reached up to 96.57% after 90 min of treatment by PS oxidation A higher PS concentration favored Cu-EDTA removal; An increase in the initial concentration of Cu-EDTA benefited PS activation, and a greater removal performance was obtained at a lower Cu-EDTA initial concentration (0.1 mmol L-1). Excessive Cu2+ accelerated Cu-EDTA removal, while superfluous EDTA suppressed it. Relatively lower initial solution pH value favored Cu-EDTA removal. SO•-4, •OH, and 1O2 displayed significant roles in the Cu-EDTA removal process, as they destroyed the chelating sites of the Cu(II) and EDTA mols.; finally small mol. organic acids, alcs., and NO-3 were produced. The released Cu(II) existed in the precipitates in the forms of Cu-based carbonates, Cu-based hydroxides, and copper oxide. A possible decomposition pathway of Cu-EDTA was proposed. Overall, multipathway activation of PS induced by heavy metal complexes could be an effective technique for the removal of the heavy metal complexes.
