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. http://pubs.sciepub.com/wjce/6/5/1/wjce-6-5-1.pdf metamizol (dipyrone) adsorption oxidative and reductive degradation
