According to the results, the degradation efficiency of perchloroethylene by H2O2\/Na2S2O8 system was 92.05% within 8 h. Due to the slow conversion between \u2261Fe3+ and \u2261Fe2+, the hydroxylamine was introduced to reduce reaction time. As for the results, the degradation efficiency of chloramphenicol in the H2O2\/Na2S2O8 system with hydroxylamine assistance was 73.31% within 100 min. Meanwhile, several key affecting factors and the kinetic models were investigated. The primary radicals were identified by electron paramagnetic resonance and radical scavenging tests. Eleven degradation products were confirmed by high-resolution liquid chromatography-mass spectrometry. The result of this study provided the theoretical basis for resource utilization of pipe deposits in water treatment in case of emerging contamination events.<\/jats:p>","DOI":"10.2166\/wst.2022.073","type":"journal-article","created":{"date-parts":[[2022,2,28]],"date-time":"2022-02-28T23:37:07Z","timestamp":1646091427000},"page":"1813-1823","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":2,"title":["Heterogeneous activation of H2O2\/Na2S2O8 with iron ore from water distribution networks for pollutant removal"],"prefix":"10.2166","volume":"85","author":[{"given":"Dan","family":"Zhong","sequence":"first","affiliation":[{"name":"School of Environment, Harbin Institute of Technology, Harbin 150090, P.R.
