Synthesis of palladium-ruthenium supported PVP(PDRU/PVP)nanomaterial as a new and selective potentiometricsensor material and its use in detection of CR(III)

In this study, PdRuO2/PVP nanomaterial was synthesized using simple and accessible methods. The synthesized nanomaterial was characterized using advanced analytical methods such as TEM, XRD and SEM. The main purpose of our study is to detect chromium, which we encounter in many areas in daily life, which is sometimes necessary for the living structure and sometimes harmful. PdRuO2/PVP nanomaterial, synthesized with the help of advanced analysis methods, was used as an ionophore in potentiometric sensor electrodes, and with its help, success was achieved in the Cr+3 ion detection phase in many aqueous samples. It was later determined that the PdRuO2/PVP sensor had various experimental parameters such as repeatability, selectivity, response time, pH, titration, potentiometric behavior and recovery in the real sample. Potentiometric behavioral characteristics were performed in concentration ranges of 1×10-6 -1.0×10-1 M. It was observed that there was no deviation in the measurements in the experiments repeated six times. The detection limit of the PdRuO2/PVP potentiometric sensor was found to be a very low value of 8.6×10-8 M. Potentiometric measurements showed that the synthesized PdRuO2/PVP ionophore was very effective in detecting Cr+3 in a wide pH range. It has also been found to have a shelf life of more than one year. As a result, it was found that the synthesized PdRuO2/PVP electrode material was highly selective, stable and applicable for Cr+3 detection.
