摘要: 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 exhibit a high specific surface area, superparamagnetism, adsorption efficiencies for phthalates. Four phthalates extracted aqueous solutions by using via solid phase extraction. Subsequent analysis was performed high-performance liquid chromatography with ultraviolet detection. analytical has good linearity in concentration range 1-200 ng/mL diethyl phthalate, diisobutyl dicyclohexyl 3-200 dipropyl phthalate. limits detection 0.10-0.62 ng/mL. Compared previous methods, lower limit, wider range, faster desorption rates. results indicate that are suitable enrichment hydrophobic substances solutions.
