The modified CPE was prepared using ferrocene (Fc) as the sensing species and paraffin oil as the binder. It is revealed that the addition of Fc can significantly shorten the response time and improve the reproducibility, selectivity, and stability of the sensor. The open circuit potential of the Fc-CPE is in linear proportion to the logarithm of TRC within the TRC concentration range from 1 mg\u2219dm\u22123 to 15 mg\u2219dm\u22123. In addition, the Fc-CPE sensor exhibits good selectivity to TRC over a wide concentration range of the possible co-exiting interference ions in seawater. The Fc-CPE electrode can be used as a convenient and reliable sensor for the continuous monitoring of TRC during the electrolytic treatment of BW.<\/jats:p>","DOI":"10.3390\/s21020350","type":"journal-article","created":{"date-parts":[[2021,1,6]],"date-time":"2021-01-06T23:33:25Z","timestamp":1609976005000},"page":"350","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Potentiometric Sensor Based on Carbon Paste Electrode for Monitoring Total Residual Chlorine in Electrolytically-Treated Ballast Water"],"prefix":"10.3390","volume":"21","author":[{"given":"Yaning","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Chemistry and Chemical Engineering, Shandong University, Jinan 250100, China"}]},{"given":"Zhihui","family":"Li","sequence":"additional","affiliation":[{"name":"Institute of Marine Science and Technology, Shandong University, Qingdao 266237, China"}]},{"given":"Xiaotong","family":"Guo","sequence":"additional","affiliation":[{"name":"Institute of Marine Science and Technology, Shandong University, Qingdao 266237, China"}]},{"given":"Guangzhou","family":"Liu","sequence":"additional","affiliation":[{"name":"Institute of Marine Science and Technology, Shandong University, Qingdao 266237, China"}]},{"given":"Shuyong","family":"Zhang","sequence":"additional","affiliation":[{"name":"Institute of Marine Science and Technology, Shandong University, Qingdao 266237, China"}]}],"member":"1968","published-online":{"date-parts":[[2021,1,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"298","DOI":"10.1139\/er-2013-0073","article-title":"A review of developments in ballast water management","volume":"22","author":"Balaji","year":"2014","journal-title":"Environ.
