description: A “half” core-shell g-C 3 N 4 /Fe 3 O 4 @ZIF-8 nanohybrid, in which Fe 3 O 4 and zeolite imidazolate framework-8 (ZIF-8) constructed the core-shell structure, was successfully fabricated via a versatile in situ growth strategy. This nanohybrid was employed for simultaneous magnetic solid-phase extraction (MSPE) of trace levels of fifteen target sulfonylurea herbicides (SUHs) in environmental water samples followed by LC-MS/MS detection. C 3 N 4 nanosheets were first prepared by liquid exfoliation of bulk g-C 3 N 4 , after which Fe 3 O 4 nanoparticles were uniformly deposited onto the surface of C 3 N 4 nanosheets, and ZIF-8 nanoparticles were grown on the surface of g-C 3 N 4 /Fe 3 O 4 by anchoring Zn 2+ on g-C 3 N 4 /Fe 3 O 4 . Owing to the synergistic effect, the hybridization of C 3 N 4 and ZIF-8 endowed the nanohybrid with higher multi-target adsorption ability for SUHs compared to pure C 3 N 4 or ZIF-8. The separation as well as the enrichment processes were facilitated using Fe 3 O 4 as a magnetic core. The influence of various parameters on MSPE efficiency, including adsorbent dosage, extraction time, solution pH, and desorption solvent and its volume, was investigated in detail. Under optimal conditions, the MSPE coupled with LC-MS/MS exhibited good linearity ranging from 0.5 to 100 μg L −1 with correlation coefficients ( R 2 ) ≥ 0.9919, high sensitivity with low limits of detection (LODs) of 0.005–0.141 μg L −1 and satisfactory recoveries of 67.4–105.5% with relative standard deviations (RSDs)
