Core–shell magnetic carbon microspheres were synthesized by a simple hydrothermal method and used as a novel magnetic solid‐phase extraction adsorbent for the sensitive determination of polybrominated diphenyl ethers in environmental water samples. Gas chromatography with negative chemical ionization mass spectrometry was adopted for the detection. Box–Behnken design was used to investigate and optimize important magnetic solid‐phase extraction parameters through response surface methodology. Under the optimal conditions, low limits of detection (0.07–0.17 ng·L −1 ), a wide linear range (1–1000 ng·L −1 ), and good repeatability (0.80–4.58%) were achieved. The developed method was validated with several real water samples, and satisfactory results were obtained in the range of 72.8–97.9%. These results indicated that core–shell magnetic carbon microspheres have great potential as an adsorbent for the magnetic solid‐phase extraction of polybrominated diphenyl ethers at trace levels from environmental water samples.
