Ephedrine psychoactive substances pose potential risks to aquatic ecosystems, making it crucial to develop reliable methods for their detection in water bodies.
A new UPLC-MS/MS method was created to accurately and efficiently quantify three ephedrine substances in sewage, optimizing various conditions for solid-phase extraction and chromatography.
The method demonstrated strong linearity, low detection limits, and high recovery rates, proving effective for analyzing contaminated surface water and domestic sewage samples.
