- Abstract:
- This paper is about electrochemical investigations of nitrite (NO2-) and nitrate (NO3-) detection in water. Herein, a study based on functionalization of carbon screen-printed electrodes (CSPE) with chitosan and tetrasulfonated copper (II) phthalocyanine nanocomposite (Chit/Ts-CuPc). Cyclic voltammetry (CV) surveys were carried out with ferri/ferrocyanide probe and analytes for preliminary investigations to confirm the efficacity of the electrode’s functionalization. Differential pulse voltammetry (DPV) measurements then were performed for more precise and sensitive detection with different analytes concentrations. Further studies regarding pH optimization, electrodes kinetics and calibration curve will be performed to calculate the sensor’s figures of merits. As well as a real sample test is to be done to prove that the developed sensors are very promising for effective nitrite and nitrate detection.
