In this work, we reported a novel all-solid-state silicate ISE, using an Ag\/Pb\/PbSiO3 electrode. This electrode responded to aqueous SiO32\u2212 with a reasonable slope of \u221231.34 mV\/decade and a good reproductivity. The linear range covered from 10\u22125 M to 10\u22121 M, for the Na2SiO3 solutions and the response time was generally less than 5 s. Its potentiometric response to pH and silicate indicated that the prepared electrode was sensitive to silicate, rather than pH. Compared to the traditional liquid ISE, our all-solid-state silicate electrode was resistant to high pressure and could be used in situ, in deep water. In addition, the miniaturized electrodes (diameter of 0.4 mm and a length of 2\u20133 cm) could be easily integrated into a multi-modal sensor, which could simultaneously determine multiple parameters. Our prepared silicate ISE could potentially be used to determine the presence of silicate in a low-chloride aqueous environment, where the ISE exhibited better selectivity for silicate, over interfering ions such as, SO42\u2212, NO3\u2212, CH3COO\u2212, CO32\u2212, and PO43\u2212.<\/jats:p>","DOI":"10.3390\/s19030525","type":"journal-article","created":{"date-parts":[[2019,1,29]],"date-time":"2019-01-29T03:40:55Z","timestamp":1548733255000},"page":"525","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":8,"title":["An All-Solid-State Silicate Ion-Selective Electrode Using PbSiO3 as a Sensitive Membrane"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1270-4799","authenticated-orcid":false,"given":"Rongrong","family":"Wu","sequence":"first","affiliation":[{"name":"Ocean College, Zhejiang University, Zhoushan 316021, China"},{"name":"Key Laboratory of Submarine Geosciences, State Oceanic Administration, Hangzhou 310012, China"},{"name":"Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou 310012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9148-8309","authenticated-orcid":false,"given":"Xue-Gang","family":"Chen","sequence":"additional","affiliation":[{"name":"Ocean College, Zhejiang University, Zhoushan 316021, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chunhui","family":"Tao","sequence":"additional","affiliation":[{"name":"Ocean College, Zhejiang University, Zhoushan 316021, China"},{"name":"Key Laboratory of Submarine Geosciences, State Oceanic Administration, Hangzhou 310012, China"},{"name":"Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou 310012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuanfeng","family":"Huang","sequence":"additional","affiliation":[{"name":"Shandong SEI Science &amp; Technology Co., Ltd., Jinan 250002, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying","family":"Ye","sequence":"additional","affiliation":[{"name":"Ocean College, Zhejiang University, Zhoushan 316021, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiujin","family":"Wang","sequence":"additional","affiliation":[{"name":"Ocean College, Zhejiang University, Zhoushan 316021, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yifan","family":"Zhou","sequence":"additional","affiliation":[{"name":"Ocean College, Zhejiang University, Zhoushan 316021, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Quan","family":"Jin","sequence":"additional","affiliation":[{"name":"Ocean College, Zhejiang University, Zhoushan 316021, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wei","family":"Cai","sequence":"additional","affiliation":[{"name":"Key Laboratory of Submarine Geosciences, State Oceanic Administration, Hangzhou 310012, China"},{"name":"Second Institute of Oceanography, Ministry of Natural Resources, Hangzhou 310012, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2019,1,27]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1157","DOI":"10.1016\/S0039-9140(02)00205-9","article-title":"A flow injection-ETAAS system for the on-line determination of total and dissolved silica in waters","volume":"58","author":"Burguera","year":"2002","journal-title":"Talanta"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"21","DOI":"10.3354\/meps240021","article-title":"Eutrophication and vertical flux: A critical evaluation of silicate addition","volume":"240","author":"Svensen","year":"2002","journal-title":"Mar.
