Patent number: 10324061Abstract: A method of determining a concentration of phenol and/or a phenol derivative in a first solution. The method includes (a) subjecting a graphite pencil electrode system comprising a graphite pencil working electrode, a counter electrode, and a reference electrode to cyclic voltammetry in a second solution such that a surface of the graphite pencil working electrode is charged by the cyclic voltammetry to form a charged surface, (b) contacting the charged surface of the graphite pencil working electrode with the first solution for sufficient time to electropolymerize the phenol and/or the phenol derivative on the charged surface in open circuit fashion, and (c) determining the concentration of the phenol and/or the phenol derivative in the first solution, wherein the amount of the electropolymerized phenol and/or the electropolymerized phenol derivative formed on the charged surface correlates with the concentration of the phenol and/or the phenol derivative in the first solution.Type: GrantFiled: June 5, 2018Date of Patent: June 18, 2019Assignee: King Fahd University of Petroleum and MineralsInventors: Abdel-Nasser M. Kawde, Azeem A. Rana
