Determinación y cuantificación electroquímica simultánea de paracetamol y levofloxacina mediante electrodo de platino

Abstract

At present there is a growing interest in the short and long term repercussions of emerging pollutants in the environment and in people's health. However, although a large number of studies have already been reported that demonstrate the toxic effects generated by these pollutants and that several international organizations, such as the World Health Organization and the United States Environmental Protection Agency, have already alerted of the possible risks of continuing with the uncontrolled incorporation of these compounds into the water bodies, most of them are not yet regulated. There is a long list of emerging pollutants within which are the pharmaceutical products that have aroused the interest of the scientific community in recent years for their toxicity in aquatic organisms. It is difficult to know the general behavior of drugs and their impact on different ecosystems because they are composed of a number of synthetic and natural chemicals that are metabolized by humans and continuously excreted. Many of these medications have been detected in wastewater treatment plants but the methods conventionally used to treat water are inefficient in the presence of these xenobiotics. Thanks to the development of new more sensitive analytical methods in the measurement of these chemical compounds it has been possible to detect trace concentrations in wastewater, sources of drinking water and groundwater, concentrations ranging from ng / L to mg / L.
