原始语种摘要: Abstract(#br)The analytical application of silica-supported graphitic carbon nitride (g-C 3 N 4 @silica) for solid-phase extraction (SPE) of fluoroquinolone (FQ) pollutants from water is presented for the first time. g-C 3 N 4 @silica was easily and quickly prepared by one-pot thermal condensation of dicyandiamide and characterized by powder X-ray diffraction, thermogravimetric analysis, scanning electron microscopy, Fourier transform infrared spectroscopy and surface area measurements. The novel composite was applied as sorbent for SPE of FQs from water prior high-performance liquid chromatography with fluorescence detection. The extraction efficiency of g-C 3 N 4 was tested in tap and surface waters at actual concentrations (10–100ngL −1 )....
