Paraules clau: Dispersive solid-phase extraction Environmental water samples hypercrosslinked magnetic particles
Resum: This work presents a new extraction material, namely, Q-100, based on hyper-crosslinked magnetic particles, which was tested in dispersive solid-phase extrac-tion for a group of sweeteners from environmental samples. The hypercrosslinkedQ-100 magnetic particles had the advantage of suitable pore size distribution andhigh surface area, and showed good retention behavior toward sweeteners. Differentdispersive solid-phase extraction parameters such as amount of magnetic particles orextraction time were optimized. Under optimum conditions, Q-100 showed suitableapparent recovery, ranging in the case of river water sample from 21 to 88% for allthe sweeteners, except for alitame (12%). The validated method based on dispersivesolid-phase extraction using Q-100 followed by liquid chromatography with tandemmass spectrometry provided good linearity and limits of quantification between 0.01and 0.1 μg/L. The method was applied to analyze samples from river water and efflu-ent wastewater, and four sweeteners (acesulfame, saccharin, cyclamate, and sucralose)were found in both types of sample.
