Natural metal sulfides as electrochemical sensors for redox titrations in γ-butyrolactone and propylene carbonate

Application of pyrite and chalcopyrite as sensor electrode for amperometric detection and measurement of hydrogen peroxide

“…Due to their excellent characteristics such as semiconductivity, non-toxicity, and availability in the nature pyrite and chalcopyrite have recently been used in various electrochemical applications in the form of solid state sensor materials. [33][34][35][36] In this study, the natural minerals (pyrite and chalcopyrite) were used as the working electrode to detect the H 2 O 2 in aqueous solution. The main purpose of this study was to further explore analytical applications of pyrite and chalcopyrite electrodes, with a focus on developing an inexpensive, rapid and convenient method for the determination of biologically important compound, H 2 O 2 .…”
