Solid-phase extraction (SPE) is one of the most commonly used technique for aqueous sample preconcentration, especially for tracing organic pollutants (e.g. pharmaceuticals and personal care products, PPCPs). However, the diversity of PPCPs proposes high demand for the compatibility of hydrophilicity and hydrophobicity of the SPE adsorbents. In this study, a new hydrophilic resin with good compatibility was successfully synthesized based on poly (N-vinyl pyrrolidone-divinylbenzene). This resin, named GCHM, was used for SPE packing. Subsequently, 44 representative PPCPs (10 classes) in complex environmental matrix were detected to evaluate the absolute recovery of two SPE cartridges (GCHM and Oasis® HLB) by UPLC-MS/MS. Twenty-one PPCPs with absolute recoveries ranging from 80% to 120% were detected using GCHM, while there were only 14 PPCPs detected for Oasis® HLB. The average absolute recovery of 44 PPCPs was 75.6% using GCHM, indicating a better performance than the commercial Oasis® HLB under optimal conditions.
