Poly(ionic liquid)‐bonded magnetic nanospheres were easily synthesized and applied to the pretreatment and determination of phenolic compounds in water samples, which have detrimental effects on water quality and the health of living beings. The high affinity of poly(ionic liquid)s toward the target compounds as well as the magnetic behavior of Fe 3 O 4 were combined in this material to provide an efficient and simple magnetic solid‐phase extraction approach. The adsorption behavior of the poly(ionic liquid)‐bonded magnetic nanospheres was examined to optimize the synthesis. Different parameters affecting the magnetic solid‐phase extraction of phenolic compounds were assessed in terms of adsorption and recovery. Under the optimal conditions, the proposed method showed excellent detection sensitivity with limits of detection in the range of 0.3–0.8 ng/mL and precision in the range of 1.2–3.3%. This method was also applied successfully to the analysis of real water samples; good spiked recoveries over the range of 82.5–99.2% were obtained.
