A drastic increase in pharmaceuticals consumption has resulted in a high load of pharmaceuticals in wastewater, resulting in an obvious need for detoxification. Metamizol is a typical representative of an analgesic non-steroidal agent that hydrolyzes into 4-Methylantipyrine (4-MAA). In this article, we show some simple adsorption, oxidation and reduction experiments that can either collect or degrade 4-MAA and some of its related metabolism products. The main successful method in detoxifying these substances is shown to be reduction at moderate temperature.
Vorgänge an Elektroden lassen sich gleichzeitig elektrochemisch und spektroskopisch beobachten, wenn Absorption oder Lumineszenz von Substanzen während eines Potenzialdurchlaufs gemessen werden. Die Versuchsaufbauten dafür müssen nicht teuer sein. Experimente mit einfachen Geräten eignen sich für den Chemieunterricht in Schulen.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
