| Popis: | In this paper, a novel polymerized fiber doped with metal–organic frameworks (UIO-66(Zr)-NH 2 ) was developed in a capillary by microwave irradiation. The fiber was successfully prepared using 4-vinyl pyridine as the monomer and ethylene glycol dimethacrylate as the cross-linker to reinforce its durability. The resultant fiber was applied to extract sulfonylurea herbicides from environmental soil and water samples before analysis with high-performance liquid chromatography. The optimization of different parameters affecting solid-phase microextraction procedure was carried out. Under the optimum experimental conditions, the extraction capability of the hybrid fiber was two times greater than that of the polymer fiber without UIO-66(Zr)-NH 2 .The proposed hybrid fiber extraction method exhibited low detection limits (0.19–1.79 µg/l), good precision ( |
