Firstly, a glassy carbon electrode (GCE) was modified with nontoxic sodium carboxymethyl cellulose (CMC) by a simple drop-casting method, which was applied to detect cadmium by differential pulse anodic stripping voltammetry (DPASV) in a solution containing both target cadmium and eco-friendly bismuth ions, based on a quick electro-codeposition of these two metal ions on the surface of the modified electrode (CMC-GCE). Investigated by scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and Fourier transform infrared spectroscopy (FT-IR), both CMC (with good film-forming ability) and bismuth (with well-defined stripping signal) were found to be well complexed with target cadmium, leading to vital signal amplification for cadmium detection at a sub-nanomolar level. Under the optimal conditions, the proposed sensor exhibited a good linear stripping signal response to cadmium (\u2161) ion, in a concentration range of 0.001 \u03bcmol\/L\u20131 \u03bcmol\/L with a limit of detection of 0.75 nmol\/L (S\/N = 3). Meanwhile, the results demonstrate that this novel electrochemical sensor has excellent sensitivity and reproducibility, which can be used as a promising detection technique for testing natural samples such as tap water.<\/jats:p>","DOI":"10.3390\/s19245482","type":"journal-article","created":{"date-parts":[[2019,12,12]],"date-time":"2019-12-12T11:06:41Z","timestamp":1576148801000},"page":"5482","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":35,"title":["Synergetic Sensing Effect of Sodium Carboxymethyl Cellulose and Bismuth on Cadmium Detection by Differential Pulse Anodic Stripping Voltammetry"],"prefix":"10.3390","volume":"19","author":[{"given":"Jingheng","family":"Ning","sequence":"first","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Luo","sequence":"additional","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Faxiang","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shouen","family":"Huang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jianhui","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongmin","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donglin","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donger","family":"Chen","sequence":"additional","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jiaqian","family":"Wei","sequence":"additional","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yongle","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Chemistry and Food Engineering, Changsha University of Science &amp; Technology, Changsha 410110, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,12]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2673","DOI":"10.1021\/ac303143x","article-title":"Electrochemical detection of arsenic (III) completely free from noble metal: Fe3O4 microspheres-room temperature ionic liquid composite showing better performance than gold","volume":"85","author":"Gao","year":"2013","journal-title":"Anal.
