However, to maintain the catalytic activity of Mn(II) ion, solution acidity has to be kept below pH 4, which is difficult to maintain in practice. Moreover, Mn(II)\/sulfite reaction is a strongly oxygen-dependent process, and purging air into reaction solution is another extra cost. To solve the above issues, we devised to implement electrolysis into Mn(II)\/sulfite (i.e., electro\/Mn(II)\/sulfite process) for organic compound (bisphenol A, BPA) oxidation. It was revealed that, under near-neutral conditions (pH 6), the removal rate of 10 \u03bcM BPA was increased from 46.3%, by Mn(II)\/sulfite process, to 94.2% by electro\/Mn(II)\/sulfite process. The enhancement of BPA removal after implementation of electrolysis to Mn(II)\/sulfite process was investigated, and concluded to be a result of several pathways. In detail, the produced oxygen from water electrolysis, direct sulfite oxidation on anode, and local acidic pH at anode vicinity together play a role in promoting SO4\u2022\u2212 production and, therefore, contaminant removal. Radical-scavenging assays confirmed the dominant role of SO4\u2022\u2212 in electro\/Mn(II)\/sulfite process.<\/jats:p>","DOI":"10.3390\/w11081608","type":"journal-article","created":{"date-parts":[[2019,8,2]],"date-time":"2019-08-02T11:58:16Z","timestamp":1564747096000},"page":"1608","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Electrolysis-Assisted Mn(II)\/Sulfite Process for Organic Contaminant Degradation at Near-Neutral pH"],"prefix":"10.3390","volume":"11","author":[{"given":"Lixin","family":"Jia","sequence":"first","affiliation":[{"name":"College of Sports, Xi\u2019an University of Architecture and Technology, Xi\u2019an 710055, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xingwang","family":"Pei","sequence":"additional","affiliation":[{"name":"College of Civil Engineering, Xi\u2019an University of Architecture &amp; Technology, Xi\u2019an 710055, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fei","family":"Yang","sequence":"additional","affiliation":[{"name":"College of Civil, Environmental and Geodetic Engineering, The Ohio State University, Columbus, OH 43210, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,8,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1637","DOI":"10.1063\/1.555843","article-title":"Reduction Potentials of One-Electron Couples Involving Free Radicals in Aqueous Solution","volume":"18","author":"Wardman","year":"1989","journal-title":"J.
