The structure of the synthesized Schiff base L was characterized by FT-IR, 1H NMR and 13C NMR. Optical characteristics were addressed by UV-Visible spectroscopy and Photoluminescence (PL) measurements. PL demonstrated that L displays a \u201cturn-off\u201d type fluorescence quenching in the presence of Zn2+ ion in aqueous solution, indicating its ability to preferentially coordinate this ion. Based on these findings, an L-M (where M is a suitable membrane) modified screen-printed carbon electrode (SPCE) was developed to evaluate the electrochemical behavior of the Schiff base (L) with the final objective of undertaking the electroanalytical determination of Zn ions in water. Using various electrochemical techniques, the modified L-M\/SPCE sensor demonstrates high sensitivity and selectivity to Zn ions over some common interferents ions, such as Ca2+, Mg2+, K+, Ni++ and Cd++. The potentiometric response of the L-M\/SPCE sensor to Zn ions was found to be linear over a relatively wide concentration range from 1 \u03bcM to 100 mM.<\/jats:p>","DOI":"10.3390\/s22030900","type":"journal-article","created":{"date-parts":[[2022,1,25]],"date-time":"2022-01-25T21:07:11Z","timestamp":1643144831000},"page":"900","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":44,"title":["On the Electroanalytical Detection of Zn Ions by a Novel Schiff Base Ligand-SPCE Sensor"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1551-359X","authenticated-orcid":false,"given":"Viviana","family":"Bressi","sequence":"first","affiliation":[{"name":"Department of Engineering, University of Messina, I-98166 Messina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zahra","family":"Akbari","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Messina, I-98166 Messina, Italy"},{"name":"Department of Chemistry, Yasouj University, Yasouj 7591874831, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8897-4683","authenticated-orcid":false,"given":"Morteza","family":"Montazerozohori","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Yasouj University, Yasouj 7591874831, Iran"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2844-1441","authenticated-orcid":false,"given":"Angelo","family":"Ferlazzo","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Messina, I-98166 Messina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2190-0035","authenticated-orcid":false,"given":"Daniela","family":"Iannazzo","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Messina, I-98166 Messina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4081-1716","authenticated-orcid":false,"given":"Claudia","family":"Espro","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Messina, I-98166 Messina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8999-060X","authenticated-orcid":false,"given":"Giovanni","family":"Neri","sequence":"additional","affiliation":[{"name":"Department of Engineering, University of Messina, I-98166 Messina, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,1,25]]},"reference":[{"key":"ref_1","unstructured":"Furniss, B.S., Hannaford, A.J., Smith, P.W.J., and Tatchell, A.R.
