AB  - This paper reports a new variant of sample clean-up procedure based on 
      miniaturized matrix solid phase dispersion (MSPD) combining with water compatible 
      magnetic molecularly imprinted polymers (MMIP) for preconcentration of melamine 
      from milk samples prior high-performance liquid chromatography with UV detection. 
      By employing MMIP as dispersant sorbent matrix interferences could be eliminated 
      completely and the column packing step was interestingly omitted that decreasing 
      in glassware expenditure, labor effort and extraction time which cause 
      improvement of the method performance. In order to investigate the functionality, 
      morphology and magnetic properties of the prepared MMIP, it was fully 
      characterized by FT-IR, VSM, SEM, and TEM. Multivariate optimization was applied 
      as a versatile statistical approach for evaluating the influence of the main 
      variables and their interactions on extraction efficiency. Under optimized 
      conditions, the proposed method exhibited a wide linear response in the 
      concentration range of 250.0-5000.0 mug L(-1), satisfactory recoveries for all 
      samples (86.6% </=), and supreme repeatability (RSD less than 6.3%) were achieved 
      as well. The low limit of detection close to 67.0 mug L(-1) implied high ability 
      of proposed method for isolation of melamine from complicate milk sample. These 
      befitting results demonstrated that the developed method is unique in terms of 
      the facility, rapidly and least solvent consumption as well as accurate analysis 
      of melamine at trace levels.
