Ion selective electrodes (ISEs) have been commonly utilized for this purpose, although the presence of interfering ions (potassium and sodium in the case of NH4+-ISE) represents a handicap in terms of the measurement quality. Furthermore, random malfunctions may give rise to incorrect measurements. Bearing all of that in mind, a smart ammonium sensor with enhanced features has been developed and tested in water samples, as demonstrated and commented on in detail following the presentation of the complete set of experimental measurements that have been successfully carried out. This has been achieved through the implementation of an expert system that supervises a set of ISEs in order to (a) avoid random failures and (b) reject interferences. Our approach may also be suitable for in-line monitoring of the water quality through the implementation of wireless sensor networks.<\/jats:p>","DOI":"10.3390\/s20247102","type":"journal-article","created":{"date-parts":[[2020,12,13]],"date-time":"2020-12-13T23:39:36Z","timestamp":1607902776000},"page":"7102","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["A New Ammonium Smart Sensor with Interference Rejection"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3879-9826","authenticated-orcid":false,"given":"Juan V.","family":"Capella","sequence":"first","affiliation":[{"name":"Instituto de las Tecnolog\u00edas de la Informaci\u00f3n y Comunicaciones ITACA, Universitat Polit\u00e8cnica de Val\u00e8ncia, Camino de Vera s\/n, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3639-8420","authenticated-orcid":false,"given":"Alberto","family":"Bonastre","sequence":"additional","affiliation":[{"name":"Instituto de las Tecnolog\u00edas de la Informaci\u00f3n y Comunicaciones ITACA, Universitat Polit\u00e8cnica de Val\u00e8ncia, Camino de Vera s\/n, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0558-7683","authenticated-orcid":false,"given":"Jos\u00e9 C.","family":"Campelo","sequence":"additional","affiliation":[{"name":"Instituto de las Tecnolog\u00edas de la Informaci\u00f3n y Comunicaciones ITACA, Universitat Polit\u00e8cnica de Val\u00e8ncia, Camino de Vera s\/n, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rafael","family":"Ors","sequence":"additional","affiliation":[{"name":"Instituto de las Tecnolog\u00edas de la Informaci\u00f3n y Comunicaciones ITACA, Universitat Polit\u00e8cnica de Val\u00e8ncia, Camino de Vera s\/n, 46022 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Miguel","family":"Peris","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Universitat Polit\u00e8cnica de Val\u00e8ncia, 46071 Valencia, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,12,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"282","DOI":"10.1016\/j.trac.2005.12.002","article-title":"A guide for selecting the most appropriate method for ammonium determination in water analysis","volume":"25","year":"2006","journal-title":"TrAC Trends Anal.
