Sumario:In this work, a magnetic graphene oxide-ultrathin metal–organic framework composite (Fe(3)O(4)@SiO(2)-GO-Ni-MOF) was synthesized for the first time. Employing Fe(3)O(4)@SiO(2)-GO-Ni-MOF composite as extractant, a novel method for the separation and analysis of the pesticide epoxiconazole was established with the assistance of high performance liquid chromatography (HPLC). The adsorption mechanisms were studied including by adsorption kinetics, thermodynamic parameters and adsorption isotherms. The experimental results showed that this method was convenient, operable, effective and practical for the extraction and determination of epoxiconazole in real samples.
