AB  - A novel, cost-effective and simple solid phase extraction (SPE) method, by using 
      a syringe connected with a nylon membrane filter as the adsorbent container, was 
      developed for the extraction of triazine herbicides from Radix Paeoniae Alba 
      (RPA) samples. The selective molecularly imprinted polymers (MIPs) synthesized 
      with the template of atrazine were employed as the adsorbents for the enrichment 
      and purification of analytes. The extraction parameters, including the volume and 
      type of loading solvent, the type of washing solvent and eluting solvent, were 
      investigated. Under the optimized conditions, the final extracts were analyzed by 
      ultra-fast liquid chromatography (UFLC). Recoveries of the developed method range 
      from 92.4% to 107.3% with intra- and inter-day relative standard deviations 
      (RSDs) lower than 8.2%. The calibration curve is linear in the concentration 
      range of 0.005-2.4 microg g(-1) for desmetryn, atrazine and terbumeton, and 0.005-1.5 
      microg g(-1) for dimethametryn and dipropetryn, with the correlation coefficient 
      (R(2)) higher than 0.9995. The limits of detection (LODs) of five triazine 
      herbicides are in the range of 0.09-0.39 ng g(-1), which are lower than the 
      maximum residue levels (MRLs) established by various official organizations. 
      Analytical results of three real Radix Paeoniae Alba samples indicate that the 
      proposed method is cost-effective and easy-to-use than other routine pretreatment 
      methods.
