Concentration of cyanide, Cu, Ni, Zn, and Cr was largely decreased by EC within 5 min. When the reaction time was extended, removal of residual cyanide, Cu, and Ni was limited. In H2O2 oxidation, the concentration of cyanide decreased from initial 75 to 12 mg L\u22121 in 30 min. The effluents from the H2O2 oxidation were further treated by EC or anodic Fenton. In EC, the concentration of total cyanide, Ni, and Cu decreased to below 0.3, 0.5, and 1.5 mg L\u22121, respectively. Removal efficiency of chemical oxygen demand by EC was less than 20.0%. By contrast, there was 73.5% reduction by the anodic Fenton process with 5 mM H2O2 at 30 min; this can be attributed to the oxidation induced by hydroxyl radicals generated by the reaction of H2O2 with the electrogenerated Fe2+. Meanwhile, residual cyanide, Cu, and Ni can also be efficiently removed. Transformation of organic components in various processes was analyzed using UV-visible and fluorescence excitation-emission spectra.<\/jats:p>","DOI":"10.2166\/wst.2013.296","type":"journal-article","created":{"date-parts":[[2013,9,24]],"date-time":"2013-09-24T09:33:23Z","timestamp":1380015203000},"page":"1329-1335","update-policy":"https:\/\/doi.org\/10.2166\/iwapcrossmarkpolicypage","source":"Crossref","is-referenced-by-count":27,"title":["Efficient treatment of an electroplating wastewater containing heavy metal ions, cyanide, and organics by H2O2 oxidation followed by the anodic Fenton process"],"prefix":"10.2166","volume":"68","author":[{"given":"Xu","family":"Zhao","sequence":"first","affiliation":[{"name":"State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, 100085, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Haidong","family":"Wang","sequence":"first","affiliation":[{"name":"State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, 100085, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fayuan","family":"Chen","sequence":"first","affiliation":[{"name":"State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, 100085, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ran","family":"Mao","sequence":"first","affiliation":[{"name":"State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, 100085, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huijuan","family":"Liu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, 100085, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiuhui","family":"Qu","sequence":"first","affiliation":[{"name":"State Key Laboratory of Environmental Aquatic Chemistry, Research Center for Eco-Environmental Sciences, Chinese Academy of Sciences, Beijing, 100085, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"945","container-title":["Water Science and Technology"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/iwaponline.com\/wst\/article-pdf\/68\/6\/1329\/472733\/1329.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"syndication"},{"URL":"http:\/\/iwaponline.com\/wst\/article-pdf\/68\/6\/1329\/472733\/1329.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2020,3,28]],"date-time":"2020-03-28T02:31:15Z","timestamp":1585362675000},"score":1,"resource":{"primary":{"URL":"https:\/\/iwaponline.com\/wst\/article\/68\/6\/1329\/17959\/Efficient-treatment-of-an-electroplating"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2013,9,1]]},"references-count":0,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2013,9,1]]}},"URL":"https:\/\/doi.org\/10.2166\/wst.2013.296","relation":{},"ISSN":["0273-1223","1996-9732"],"issn-type":[{"value":"0273-1223","type":"print"},{"value":"1996-9732","type":"electronic"}],"subject":[],"published-other":{"date-parts":[[2013,9,1]]},"published":{"date-parts":[[2013,9,1]]}}}
