Modified on a cheap glass carbon electrode, these MnFe2O4\/Au hybrid nanospheres show favorable sensitivity (0.315 \u03bcA\/ppb) and limit of detection (LOD) (3.37 ppb) toward As(III) under the optimized conditions in 0.1 M NaAc-HAc (pH 5.0) by depositing for 150 s at the deposition potential of \u22120.9 V. No obvious interference from Cd(II) and Hg(II) was recognized during the detection of As(III). Additionally, the developed electrode displayed good reproducibility, stability, and repeatability, and offered potential practical applicability for electrochemical detection of As(III) in real water samples. The present work provides a potential method for the design of new and cheap sensors in the application of electrochemical determination toward trace As(III) and other toxic metal ions.<\/jats:p>","DOI":"10.3390\/s16060935","type":"journal-article","created":{"date-parts":[[2016,6,23]],"date-time":"2016-06-23T18:29:50Z","timestamp":1466706590000},"page":"935","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["Electrochemical Sensing toward Trace As(III) Based on Mesoporous MnFe2O4\/Au Hybrid Nanospheres Modified Glass Carbon Electrode"],"prefix":"10.3390","volume":"16","author":[{"given":"Shaofeng","family":"Zhou","sequence":"first","affiliation":[{"name":"Shanxi Province Key Laboratory of Functional Nanocomposites, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaojuan","family":"Han","sequence":"additional","affiliation":[{"name":"Shanxi Province Key Laboratory of Functional Nanocomposites, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Honglei","family":"Fan","sequence":"additional","affiliation":[{"name":"Shanxi Province Key Laboratory of Higee-Oriented Chemical Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yaqing","family":"Liu","sequence":"additional","affiliation":[{"name":"Shanxi Province Key Laboratory of Functional Nanocomposites, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2016,6,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"201","DOI":"10.1016\/S0039-9140(02)00268-0","article-title":"Arsenic round the world: A review","volume":"58","author":"Mandal","year":"2002","journal-title":"Talanta"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"4836","DOI":"10.1021\/ac071064w","article-title":"Gold nanoelectrode ensembles for the simultaneous electrochemical detection of ultratrace arsenic, mercury, and copper","volume":"80","author":"Jena","year":"2008","journal-title":"Anal.
