AB  - In this study, a new metal-organic framework-monolith composite for in-tube solid 
      phase microextraction phase (IT-SPME) of fluoroquinolones (FQs) was prepared. 
      4-Vinylbenzoic acid was copolymerized with ethylenedimethacrylate in a fused 
      silica capillary to form porous monolith. After that, zeolitic imidazolate 
      frameworks (ZIF-8) were synthesized in situ within the pores and the surface of 
      the monolith by controlled layer-by-layer self-assembly of Zn(2+) and imidazole. 
      The introduction of ZIF-8 enhanced the surface area of monolith composite, and 
      thus, improving the extraction performance of IT-SPME for FQs obviously. Under 
      the optimized conditions, a highly sensitive method for the monitoring of FQs 
      residue in water and honey samples was developed by the on-line combination of 
      IT-SPME with high-performance liquid chromatography with fluorescence detection 
      (HPLC-FLD). The limits of detection (S/N = 3) for the targeted FQs in water and 
      honey samples were as low as 0.14-0.61 ng/L and 0.39-1.1 ng/L, respectively. The 
      relative standard deviations (RSDs) for intra-day and inter-day assay variability 
      were less than 10% in all samples. The established on-line IT-SPME-HPLC-FLD was 
      successfully used to detect ultra-trace FQs in environmental water and honey 
      samples. Recoveries at different spiked concentrations ranged from 80.1% to 119% 
      and 80.2-117% for water and honey samples, respectively, with satisfactory 
      reproducibility. Compared to up-to-date reported methods, the proposed approach 
      exhibits some features such as high sensitivity, convenience, partial automation, 
      low consumptions of sample and solvent.
