Accurate and frequent monitoring of NO3− levels in water bodies is crucial for human health and environment. Here, copper (Cu) thin films electrodeposited on screen-printed carbon electrodes (SPCEs) were explored as an electrochemical sensing platform for the detection of NO3− in water. Scanning electron microscopy with energy-dispersive X-Ray analysis, X-Ray diffraction analysis, and X-ray photoelectron spectroscopy was employed to characterize the morphology and composition of the thin film modified electrode. The electrochemical response of Cu thin film deposited SPCE under different pH conditions (4 to 10) and various temperature (20-60°C) was assessed using linear sweep voltammetry. The developed electrochemical sensor allowed the measurement of NO3− levels ranging from 50 to 750 µM with a sensitivity of 0.1042 µA mM-1. The sensor exhibited good detection limit in fish culture water (120 nM), reverse osmosis processed water (91 nM) and borewell water (98 nM). The sensor response was found to be stable in the presence of other interfering analytes (NO2-, K+, Na+, SO42-, Mg2+, Cl-, Fe3+, Fe2+, Mn2+, Cu2+, Zn2+). The performance of the sensor was demonstrated in water samples collected from various sources and the sensor showed an acceptable performance rates for practical applications.

Ion-selective electrodes are a popular analytical tool useful in the analysis of cations and anions in environmental, industrial and clinical samples. This paper presents an overview of new materials used for the preparation of anion-sensitive ion-selective electrodes during the last five years. Design variants of anion-sensitive electrodes, their advantages and disadvantages as well as research methods used to assess their parameters and analytical usefulness are presented. The work is divided into chapters according to the type of ion to which the electrode is selective. Characteristics of new ionophores used as the electroactive component of ion-sensitive membranes and other materials used to achieve improvement of sensor performance (e.g., nanomaterials, composite and hybrid materials) are presented. Analytical parameters of the electrodes presented in the paper are collected in tables, which allows for easy comparison of different variants of electrodes sensitive to the same ion.
