The main goal of this work is to create a highly sensitive optical sensor based on the principle of plasmon surface resonance (SPR) for inorganic salts. The experimental concept includes the creation of optical fiber probe with anion capturing agent(ACA) through the diazonium chemistry for selective-entrapping of targeted compounds and their trace amounts detection. The characterization of the obtained structures and their properties were performed using the SERS, AFM and UV-Vis methods. The created hybrid sensor structures were used to measure the presence and concentration of inorganic salts, which often occur in polluted wastewater. The proposed approach has a number of advantages, such as the possibility of real-time detection, high selectivity and sensitivity, and the possibility of miniaturization of the analytical device(s).
