Abstract
AbstractDrugs and their metabolites have become new types of pollutants, the presence of which constitutes a serious environmental problem. This article applies the established LC–MS/MS method to investigate the removal efficiency of different ratios of Fenton reagents for common drugs in wastewater. The results showed that the linearity of the 10 common drugs was good in the dynamic range of 1–100 ng/L, and the R2>0.99. The LODs and LOQs ranged from 0.01–0.443 ng/L and 0.04–1.44 ng/L, respectively. The average relative recoveries ranged from 72.99–117 %. In addition, considering the economic and application effects of chemical reagents, the optimal test dose of H2O2 in Fenton reagent was determined to be 12.5 mL. This experiment provides a simple, rapid and low‐cost LC–MS/MS method for the detection of drugs in wastewater. It also provides data reference for effective management of drug production sites and domestic wastewater pollution.
