Sulforaphane (SFN) is a natural isothiocyanate compound widely abundant in cruciferous vegetables with multiple bioactive functions. However, traditional analytical methods for the extraction and determination of SFN are cumbersome, time-consuming, low sensitivity large amounts organic solvents. Herein, novel magnetic COF-on-COFs (MB-COFs) were fabricated using Fe3O4 as core COFs-1 grown COFs-2 shell, they used efficient adsorbents dispersive solid-phase rapid quantification by combining HPLC-MS/MS. At optimal ratio to COFs-2, MB-COFs had spherical cluster-like structure rough surface, sufficient response separation (1 min). Due introduction exhibited outstanding efficiencies (92.5–97.3%), which was about 18–72% higher than that bare COFs. Moreover, showed good adsorption capacity (Qm 18.0 mg/g), (5 min) desorption (30 s) SFN, favorable reusability (≥7 cycles) virtue their unique hierarchical porous structure. The kinetic data well fitted pseudo-second-order, Ritchie-second-order, intra-particle diffusion, Elovich models, while isotherm highly consistent Langmuir, Temkin, Redlich–Peterson models. Finally, under optimized conditions, developed method wide linear range (0.001–0.5 mg/L), high (limits 0.18–0.31 μg/L), satisfactory recoveries (82.2–96.2%) precisions (1.8–7.9%), negligible matrix effect (0.82–0.97). Compared previous methods, proposed faster more sensitive significantly reduces use solvents, can achieve detection large-scale samples practical scenarios. This work reveals potential analysis vegetables.
