摘要：
In this paper, a green proline choline ionic liquid ([Ch][Pro])-modified magnetic graphene oxide was used as the solid-phase extractant (Fe3O4@SiO2@GO@[Ch][Pro]), which was characterized by FIR and hysteresis loops. A novel method for the determination of fenthion by magnetic solid-phase extraction with HPLC was established. Factors affecting extraction and elution performance were investigated, such as the amount of extractant, pH of the solution, the time and temperature of extraction and elution. Under the best conditions, a good linearity (R-2 = 0.9987) equation was obtained with the concentration range 0.02-10 mu g mL(-1). This method has been successfully applied to the determination of fenthion in apple samples and water samples.
