Several ISEs were conditioned and tested for the selection of common ions. The electrodes based on these ionophores showed a good potentiometric response for Hg<jats:sup>2+<\/jats:sup> ions over a wide concentration range of 5.0\u00d710<jats:sup>\u20105<\/jats:sup>\u20101.0\u00d710<jats:sup>\u20101<\/jats:sup>M with near\u2010Nernstian slopes. Stable potentiometric signals were obtained within a short time period of 20 s. The detection limits, the working pH range of the electrodes were 1.0\u00d710<jats:sup>\u20105<\/jats:sup> M and 1.6\u20104.4 respectively. The electrodes showed better selectivity for Hg<jats:sup>2+<\/jats:sup> ions over many of the alkali, alkaline\u2010earth and heavy metal ions. Also sharp end points were obtained when these sensors were used as indicator electrodes for the potentiometric titration of Hg<jats:sup>2+<\/jats:sup> ions with iodide ions.<\/jats:p>","DOI":"10.1002\/adic.200790080","type":"journal-article","created":{"date-parts":[[2007,7,16]],"date-time":"2007-07-16T16:47:46Z","timestamp":1184604466000},"page":"959-970","source":"Crossref","is-referenced-by-count":11,"title":["Mercury(II) Ion\u2010Selective Electrodes Based on Heterocyclic Systems"],"prefix":"10.1002","volume":"97","author":[{"given":"Rakesh Kumar","family":"Mahajan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pallavi","family":"Sood","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mohinder Pal","family":"Mahajan","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alka","family":"Marwaha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2007,7,16]]},"reference":[{"key":"e_1_2_1_2_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac00084a010"},{"key":"e_1_2_1_3_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac00091a033"},{"key":"e_1_2_1_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-2670(02)01520-9"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0925-4005(01)00942-X"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0039-9140(02)00473-3"},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1521-4109(199902)11:2<81::AID-ELAN81>3.0.CO;2-Q"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1021\/ac970133b"},{"key":"e_1_2_1_9_2","doi-asserted-by":"publisher","DOI":"10.1039\/an9861100891"},{"key":"e_1_2_1_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0003-2670(98)00382-1"},{"key":"e_1_2_1_11_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0039-9140(03)00036-5"},{"key":"e_1_2_1_12_2","doi-asserted-by":"publisher","DOI":"10.1002\/elan.1140030821"},{"key":"e_1_2_1_13_2","first-page":"418","volume":"12","author":"Siswanta D.","year":"1996","journal-title":"Chem.
