This document stipulates the regulations on morphine, codeine, O6-monoacetylmorphine, methamphetamine, 3,4-methylenedioxymethamphetamine (MDMA), amphetamine, benzoylecgonine, ketamine, normethylamphetamine in urban sewage. Online solid phase analysis of 13 drugs including ketamine (NK), methcathinone (MC), cocaine, 3,4-methylenedioxyamphetamine (MDA), and tetrahydrocannabinoid acid as well as their metabolites and population marker cotinine Extraction (AOE) system-ultra-performance liquid chromatography-tandem mass spectrometry detection method. The sewage samples were pH adjusted, centrifuged, filtered, enriched, purified, concentrated and detected by the multiple reaction monitoring (MRM) mode of liquid chromatography-tandem mass spectrometry through an online solid-phase extraction system. Analysis was based on retention time, mass spectrum characteristic fragment ion peaks and ion pair relative abundance ratio, and quantified by internal standard method.
