Özet

In this study, for the first time, the electro-polymerization of Direct blue15 (DB15), an azo dye, was carried out on the surface of ITO. Furthermore, the poly(DB15) surface was electrochemically decorated with Ag nanoparticles (AgNPs), and the fabricated AgNPs/PDB15 electrodes were examined as nitrate sensors. Compared to unmodified ITO electrode, the AgNPs/PDB15 electrode had greatly improved electrochemical response to nitrate reduction. The nitrate determination in a linear range from 1.0x10(-5) mol L-1 to 2.27x10(-3) mol L-1 was performed with a detection limit of 9.66 mu M. The synthesized electrode is a promising sensor for the electrochemical detection of nitrate pollutants in water.
