AB  - Due to the endocrine disrupting properties, organic UV filters have been a great 
      risk for humans and other organisms. Therefore, development of accurate and 
      effective analytical methods is needed for the determination of UV filters in 
      environmental waters. In this work, a fast, sensitive and environmentally 
      friendly method combining magnetism-enhanced monolith-based in-tube solid phase 
      microextraction with high-performance liquid chromatography with diode array 
      detection (DAD) (ME-MB-IT/SPME-HPLC-DAD) for the online analysis of five organic 
      UV filters in environmental water samples was developed. To extract UV filters 
      effectively, an ionic liquid-based monolithic capillary column doped with 
      magnetic nanoparticles was prepared by in-situ polymerization and used as 
      extraction medium of online ME-MB-IT/SPME-HPLC-DAD system. Several extraction 
      conditions including the intensity of magnetic field, sampling and desorption 
      flow rate, volume of sample and desorption solvent, pH value and ionic strength 
      of sample matrix were optimized thoroughly. Under the optimized conditions, the 
      extraction efficiencies for five organic UV filters were in the range of 
      44.0-100%. The limits of detection (S/N=3) and limits of quantification (S/N=10) 
      were 0.04-0.26mug/L and 0.12-0.87mug/L, respectively. The precisions indicated by 
      relative standard deviations (RSDs) were less than 10% for both intra- and 
      inter-day variabilities. Finally, the developed method was successfully applied 
      to the determination of UV filters in three environmental water samples and 
      satisfactory results were obtained.
