Abstract
The weighty industrialization, rapid urbanization and the changing lifestyle have been considered as a worldwide threat, these human activities produce a huge pollutant element especially in water such as antibiotics, heavy metals etc.. Hence, the sensing and quantification of trace pollutants in aquatic system have been becoming a necessity tool to develop. In this work, we synthesis the silver metavanadate AgVO3 through solid state reaction, the obtained powder was analyzed using X-ray diffraction, infrared spectroscopy and scanning electronic microscopy to check the structure and purity of the silver metavanadate. The elaborated compound as a modifier of carbon paste electrode to investigate the sensing of amoxicillin in aqueous solution by means of square wave voltammetry. The effect of electrochemical and chemical parameters on the current intensity was optimized. Under optimized conditions, the prepared electrode had a detection limit of 0.731µM. The interaction between amoxicillin molecule and AgVO3 surface was also investigated, which shows spontaneous adsorption process.
