| 英文摘要 | The ubiquitous distribution of halogenated aromatic pollutants (XAr) coupled with their carcinogenicity has raised public concerns on their potential risks to both human health and the ecosystem. Recently, advanced oxidation processes (AOPs) have been employed as an "environmental-green" technology for treatment and degradation of such recalcitrant and highly toxic XAr. During our study on the molecular mechanism of metal-independent hydroxyl radicals (center dot OH) production by halogenated quinones and H2O2, we unexpectedly find that an unprecedented center dot OH-dependent two. step intrinsic chemiluminescene (CL) can be produced by H2O2 and tetrachloro-p-benzoquinone, which is the major carcinogenic metabolite of the widely-used wood preservative pentachlorophenol. We further find that center dot OH-producing AOPs-mediated degradation of pentachlorophenol and all other XAr could produce intrinsic CL that is directly dependent on the formation of the extremely reactive center dot OH-A systematic structure. activity relationship study for all 19 chlorinated phenols demonstrates that the CL increases with an increasing number of chlorine-substitution in general. More interestingly, a relatively good correlation is noticed that not only between CL intensity and chlorinated quinoid intermediates, but also between CL emission and semiquinone radicals. Taken together, we propose that center dot OH-dependent formation of quinoid intermediates, quinone. 1,2-dioxetane and electronically excited carbonyl species is responsible for this unusual intrinsic CL production. A rapid, sensitive, simple, and effective CL method has been developed to not only detect and measure trace amount of XAr in real environment, but also to provide useful information for predicting the toxicity or monitoring the degradation kinetics of XAr. These findings may have broad chemical, environmental and biological implications for future studies on remediation of other halogenated persistent organic pollutants by AOPs. |
