AB  - We aim to develop a solid-phase extraction (SPE) based on a dummy molecularly 
      imprinted polymer (MIP) and liquid chromatography-tandem quadrupole mass 
      spectrometry (LC-MS/MS) for selective determination of four pyridine carboxylic 
      acid herbicides (aminopyralid, picloram, fluroxypyr, and clopyralid) in milk 
      samples. Using picloram as the dummy template, MIP nanocomposites with highly 
      selective recognition and adsorption for the target molecule and its structural 
      analogs were successfully synthesized by precipitation polymerization. Adsorption 
      isotherms and kinetics were used to determine the adsorption performance and 
      specific recognition mechanism of both MIPs and non-molecularly imprinted 
      polymers (NIP). The Scatchard plot analysis revealed that two different binding 
      sites were formed in the MIP with maximum binding capacity (Q(max)) of 
      1171.8 mug.g(-1) and 3022.5 mug.g(-1), respectively. Recovery at three spiking 
      levels of 10, 20, and 50 mug.L(-1) ranged between 75.3 and 89.8% with relative 
      standard deviations (RSDs) <14.3%.The limit of detection (LOD) was estimated to 
      be 0.124 mug.L(-1). Finally, the feasibility of the proposed methodology was 
      successfully applied to quantify aminopyralid and another three pyridine 
      carboxylic acid herbicides in milk.
