Cetyltrimethylammonium bromide (CTAB), which formed a bilayer on the surface of the carbon paste (CP) electrode, displayed a remarkable enhancement effect for the electrochemical oxidation of NP. Moreover, the oxidation peak current of NP at the CTAB\/CP electrode demonstrated a linear relationship with NP concentration, which could be applied in the direct determination of NP. Some experimental parameters were investigated, such as external solution pH, mode and time of accumulation, concentration and modification time of CTAB and so on. Under optimized conditions, a wide linear range from 1.0 \u00d7 10\u22127 mol\u00b7L\u22121 to 2.5 \u00d7 10\u22125 mol\u00b7L\u22121 was obtained for the sensor, with a low limit of detection at 1.0 \u00d7 10\u22128 mol\u00b7L\u22121. Several distinguishing advantages of the as-prepared sensor, including facile fabrication, easy operation, low cost and so on, suggest a great potential for its practical applications.<\/jats:p>","DOI":"10.3390\/s130100758","type":"journal-article","created":{"date-parts":[[2013,1,7]],"date-time":"2013-01-07T11:07:53Z","timestamp":1357556873000},"page":"758-768","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":24,"title":["A Facile Electrochemical Sensor for Nonylphenol  Determination Based on the Enhancement Effect of Cetyltrimethylammonium Bromide"],"prefix":"10.3390","volume":"13","author":[{"given":"Qing","family":"Lu","sequence":"first","affiliation":[{"name":"MOE Key Lab of Environment and Health, Institute of Environmental Medicine, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Weina","family":"Zhang","sequence":"additional","affiliation":[{"name":"MOE Key Lab of Environment and Health, Institute of Environmental Medicine, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhihui","family":"Wang","sequence":"additional","affiliation":[{"name":"MOE Key Lab of Environment and Health, Institute of Environmental Medicine, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Guangxia","family":"Yu","sequence":"additional","affiliation":[{"name":"MOE Key Lab of Environment and Health, Institute of Environmental Medicine, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuan","family":"Yuan","sequence":"additional","affiliation":[{"name":"MOE Key Lab of Environment and Health, Institute of Environmental Medicine, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yikai","family":"Zhou","sequence":"additional","affiliation":[{"name":"MOE Key Lab of Environment and Health, Institute of Environmental Medicine, School of Public Health, Tongji Medical College, Huazhong University of Science and Technology, Wuhan 430030, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2013,1,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"253","DOI":"10.1016\/j.ecoenv.2010.10.039","article-title":"Genotoxicity of 4-nonylphenol and nonylphenol ethoxylate mixtures by the use of Saccharomyces cerevisiae D7 mutation assay and use of this text to evaluate the efficiency of biodegradation treatments","volume":"74","author":"Frassinetti","year":"2011","journal-title":"Ecotox.
