Description
Summary:Benzosulfonamides (BeSAs) are a family of compounds with a broad application as industrial chemicals: plasticizers, intermediates for pesticides and drugs or used in the production of artificial sweeteners, among others. BeSAs constitute a class of organic compounds of emerging environmental concern. However, analytical methodologies for their determination in the environment are scarce as well as there is a lack of environmental occurrence data for these substances. An analytical methodology based on pseudo-SRM liquid chromatography–tandem mass spectrometry (LC–(ESI–)MS/MS) was developed and optimized for the determination of three BeSAs (benzenesulfonamide (BSA), o-toluenesulfonamide (o-TSA) and p-toluenesulfonamide (p-TSA)) in wastewater. The solid phase extraction protocol was also carefully optimized. The method provided recoveries in the range 83–118% (three different fortification levels). Good precision (
