Sensitive Amperometric Determination of Thiocyanates at Ionic Liquid Nanohybrid Kaolinite Modified Glassy Carbon Electrode

19-Jan-2018 | Bruno Boniface Nguelo, Gustave Kenne Dedzo, Ignas Kenfack Tonle, Christian Detellier, Emmanuel Ngameni, Electroanalysis, 2018

Abstract Electrochemical sensors have been developed by modifying a glassy carbon electrode with organo‐kaolinite hybrid materials. These materials were obtained by the grafting of four ionic liquids (1‐(2‐hydroxyethyl)‐4‐benzylpyridinium chloride, 1‐(2‐hydroxyethyl)‐4‐(tert‐butyl)pyridinium ...
