AB  - In this work, a convenient and sensitive method for the determination of 
      triazoles in environmental waters was developed by on-line combining in-tube 
      solid phase microextraction (IT-SPME) and high performance liquid chromatography 
      with diode array detector (HPLC-DAD). To extract triazoles effectively, poly 
      (4-vinyl pyridine-co-ethylene dimethacrylate) monolith was in-situ fabricated and 
      utilized as the extraction phase of IT-SPME. A series of key extraction 
      parameters including desorption solvent, sample volume, adsorption and desorption 
      flow rate, pH value and ionic strength in sample matrix were optimized 
      thoroughly. Under the most favorable conditions (volume of sample, 6.0 mL; 
      adsorption flow rate, 0.2 mL/min; desorption solvent, 80.0 microL mixture of 
      ACN/water (70/30, v/v); desorption flow rate, 50.0 microL/min; sample pH value, 8.0; 
      ionic strength did not be adjusted), the developed monolith-based IT-SPME could 
      extract target analytes effectively and expected analytical merits were achieved. 
      The limits of detection (S/N = 3) and limits of quantification (S/N = 10) were in 
      the ranges of 0.014-0.031 microg/L and 0.11-0.074 microg/L, respectively. Satisfactory 
      method reproducibility was obtained by intra-day and inter-day precisions, with 
      relative standard deviations (RSDs) lower than 10%. The optimized 
      IT-SPME-HPLC-DAD method was then applied to detect triadimenol, triazolone and 
      hexaconazole in water samples including lake, river and sewage waters. The spiked 
      recoveries were 78.9-106% and the RSDs were in the range of 0.2-7.2%. The results 
      well evidence that the proposed method is convenient, accurate, sensitive, 
      practical and environmentally friendly for the determination of triazoles in 
      environmental waters.
