For the first time a nanostructure-based iodide ion selective electrode was developed. The ZnO nanotubes were functionalized with miconazole ion exchanger and the electromotive force (EMF) was measured by the potentiometric method. The iodide ion sensor exhibited a linear response over a wide range of concentrations (1 \u00d7 10\u22126 to 1 \u00d7 10\u22121 M) and excellent sensitivity  of \u201362 \u00b1 1 mV\/decade. The detection limit of the proposed sensor was found to be 5 \u00d7 10\u22127 M. The effects of pH, temperature, additive, plasticizer and stabilizer on the potential response of iodide ion selective electrode were also studied. The proposed iodide ion sensor demonstrated a fast response time of less than 5 s and high selectivity against common organic and the inorganic anions. All the obtained results revealed that the iodide ion sensor based on functionalized ZnO nanotubes may be used for the detection of iodide ion in environmental water samples, pharmaceutical products and other real samples.<\/jats:p>","DOI":"10.3390\/s130201984","type":"journal-article","created":{"date-parts":[[2013,2,4]],"date-time":"2013-02-04T11:10:35Z","timestamp":1359976235000},"page":"1984-1997","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":47,"title":["A Selective Iodide Ion Sensor Electrode Based on Functionalized ZnO Nanotubes"],"prefix":"10.3390","volume":"13","author":[{"given":"Zafar","family":"Ibupoto","sequence":"first","affiliation":[{"name":"Department of Science and Technology, Campus Norrk\u00f6ping, Link\u00f6ping University, SE-60174 Norrk\u00f6ping, Sweden"}]},{"given":"Kimleang","family":"Khun","sequence":"additional","affiliation":[{"name":"Department of Science and Technology, Campus Norrk\u00f6ping, Link\u00f6ping University, SE-60174 Norrk\u00f6ping, Sweden"}]},{"given":"Magnus","family":"Willander","sequence":"additional","affiliation":[{"name":"Department of Science and Technology, Campus Norrk\u00f6ping, Link\u00f6ping University, SE-60174 Norrk\u00f6ping, Sweden"}]}],"member":"1968","published-online":{"date-parts":[[2013,2,4]]},"reference":[{"key":"ref_1","unstructured":"Michael, G.H., and Robert, S.G.
