Abstract

Abstract: In this work, core‐shell structured magnetic mesoporous carbon nanospheres were fabricated from the carbonization of metal‐polyphenol coordination polymer‐coated Fe3 O4 nanoparticles. The preparation method is simple, fast, versatile, and easy to scale up. Magnetic mesoporous carbon nanospheres exhibit a high specific surface area, high superparamagnetism, and high adsorption efficiencies for phthalates. Four phthalates were extracted from aqueous solutions by using magnetic mesoporous carbon nanospheres via magnetic solid phase extraction. Subsequent analysis was performed by using high‐performance liquid chromatography with ultraviolet detection. The analytical method has good linearity in the concentration range of 1–200 ng/mL for diethyl phthalate, diisobutyl phthalate, and dicyclohexyl phthalate, and 3–200 ng/mL for dipropyl phthalate. The limits of detection were in the range of 0.10–0.62 ng/mL. Compared with previous methods, this method has a lower detection limit, wider linearity range, and faster adsorption and desorption rates. The results indicate that magnetic mesoporous carbon nanospheres are suitable for the enrichment of hydrophobic substances from aqueous solutions.
