Abstract :In this study, a biomimetic selective pesticide electrochemical sensor based on copper phthalocyanine-anthraquinone hybrid insert ignore into journalissuearticles values(CuPc-AQ); was studied. Electrochemical activities based on Pc ring and anthraquinone substituent of the CuPc-AQ make it valuable material for electrochemical sensor studies in detecting of pesticides. Thin film of CuPc-AQ on ITO electrode insert ignore into journalissuearticles values(ITO/CuPc-AQ); was exposed to water samples containing eserine and carbofuran pesticides, separately. Then in order to observe the sensor behavior of the modified electrode, square wave voltammetry insert ignore into journalissuearticles values(SWV);, electrochemical impedance spectroscopy insert ignore into journalissuearticles values(EIS);, and double potential step chronocoulometry insert ignore into journalissuearticles values(DPSCC); techniques were used. When the ITO/CuPc-AQ electrode was doped with nano-platinum insert ignore into journalissuearticles values(nPt); or nano-gold insert ignore into journalissuearticles values(nAu); particles, the sensitivity of ITO/CuPc-AQ electrode increased. The lowest detection limit insert ignore into journalissuearticles values(DL); insert ignore into journalissuearticles values(1.23x10-9 mol dm-3); was obtained with ITO/CuPc-AQ-nAu electrode using electrochemical impedance spectroscopy technique.
