Effects of PS (K2S2O8) and 1.5-MACC doses on PS decomposition and total organic carbon (TOC) removal in BTCW were also studied during 360 min. The results showed that the 1.5-MACC\/PS system has a much better performance on TOC removal in BTCW than only 1.5-MACC or PS system. PS decomposition and TOC removal follow first-order kinetics in the 1.5-MACC\/PS system. The optimum condition of the 1.5-MACC\/PS system to treat BTCW is with a K2S2O8 dose of 4 g L\u22121 and 1.5-MACC dose of 5 g L\u22121. Under this condition, TOC in the PS oxidation effluent is 20.4 mg L\u22121 with a removal efficiency of 85.4%. TOC removal is a synergistic effect of adsorption and oxidation. TOC oxidation is due to the generation of \u00b7SO4\u2212 via the activation of PS by CuFe2O4 impregnated AC. The gas chromatography\u2013mass spectrometry (GC-MS) analysis revealed that phenol compounds and esters were removed significantly by the 1.5-MACC\/PS system. When 1.5-MACC was used for the fourth time in the 1.5-MACC\/PS system, the removal ratio of TOC was still over 62.2% in 360 min reaction. Thus, the 1.5-MACC\/PS system has a potential practical application in treatment of BTCW.<\/jats:p>","DOI":"10.2166\/wst.2018.069","type":"journal-article","created":{"date-parts":[[2018,2,17]],"date-time":"2018-02-17T01:20:15Z","timestamp":1518830415000},"page":"1891-1898","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":22,"title":["Advanced treatment of biologically treated coking wastewater by persulfate oxidation with magnetic activated carbon composite as a catalyst"],"prefix":"10.2166","volume":"77","author":[{"given":"Xiulan","family":"Song","sequence":"first","affiliation":[{"name":"College of Environmental Science and Engineering, Taiyuan University of Technology, Taiyuan 030024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chao","family":"Wang","sequence":"first","affiliation":[{"name":"Faculty of Science and Technology, Technological and Higher Education Institute of Hong Kong, Tsing Yi Island, Hong Kong"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Meiqin","family":"Liu","sequence":"first","affiliation":[{"name":"College of Environmental Science and Engineering, Taiyuan University of Technology, Taiyuan 030024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miao","family":"Zhang","sequence":"first","affiliation":[{"name":"College of Environmental Science and Engineering, Taiyuan University of Technology, Taiyuan 030024, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"945","published-online":{"date-parts":[[2018,2,16]]},"reference":[{"key":"2020040712483677200_WST-EM171268C1","doi-asserted-by":"crossref","first-page":"1940","DOI":"10.1021\/es103150v","article-title":"Bioaugmentation and adsorption treatment of coking wastewater containing pyridine and quinoline using zeolite-biological aerated filters","volume":"45","year":"2011","journal-title":"Environmental Science and Technology"},{"key":"2020040712483677200_WST-EM171268C2","doi-asserted-by":"crossref","first-page":"124","DOI":"10.1016\/j.cej.2017.04.094","article-title":"Monochlorophenols degradation by UV\/persulfate is immune to the presence of chloride: illusion or reality?","volume":"323","year":"2017","journal-title":"Chemical Engineering Journal"},{"issue":"3","key":"2020040712483677200_WST-EM171268C3","doi-asserted-by":"crossref","first-page":"1098","DOI":"10.1016\/j.cej.2011.05.006","article-title":"Adsorption-photocatalytic degradation of acid red 88 by supported TiO2: effect of activated carbon support and aqueous anions","volume":"171","year":"2011","journal-title":"Chemical Engineering Journal"},{"issue":"1\u20132","key":"2020040712483677200_WST-EM171268C4","first-page":"9","article-title":"Interaction of adsorption and catalytic reactions in water decontamination processes.
