چکیده انگلیسی
A unique 3D porous Cu@graphitic octahedron carbon cages were constructed by rapid room-temperature synthesis of a Cu-based metal-organic framework (MOF) with further pyrolysis in N2, which exhibited good enrichment ability for four fluoroquinolones (FQs) due to their superior chemical affinities to the target analytes. Applied Cu@graphitic octahedron carbon cages as adsorbent, a dispersive solid phase extraction (DSPE) method combined with HPLC was developed for detecting four FQs in real samples. Various parameters affecting residues FQs extraction efficiency were inquired in more detail. Under optimal conditions, the extraction recoveries of four FQs in chicken muscle, fish tissue, seawater and river water samples were in the range of 81.3∼104.3% and the RSDs (n = 5) were less than 5.2%. This method was successfully used to the determination of FQs in real samples.
