Paraules clau: Synthetic cathinones Solid-phase extraction Weak cation-exchange
Resum: Synthetic cathinones have become popular in recent years, which would explain why their determination in influent sewage samples has already been documented. In the present study a method based on solid-phase extraction followed by liquid chromatography and high resolution mass spectrometry is developed, validated and applied to determine twelve cathinones and one of their metabolites in different environmental samples including influent and effluent sewage and river water. Two cation-exchange sorbents (Oasis MCX and Oasis WCX) were compared, with better results achieved with Oasis WCX in terms of apparent recoveries (70–100%) and matrix effects (lower than −34%).
The method was validated with effluent sewage samples providing suitable figures of merit, with method
quantification limits ranging from 1 ng/L to 5 ng/L and method detection limits from 0.1 ng/L to 0.5 ng/L
for all the compounds. Of the different cathinones studied, three, namely methylone, mephedrone metabolite
and methylenedioxypyrovalerone, were quantified at concentration levels of low ng/L in each of the different
samples analysed, while a number of the other cathinones were also detected in some of the samples.
