AB  - In this work, novel dummy molecularly imprinted polymers (DMIP) with propanamide 
      as a dummy template molecule were prepared based on a green synthesis strategy of 
      less consumption of hazardous/organic reagents and at mild conditions for 
      magnetic solid-phase extraction (MSPE) of acrylamide in biscuit samples, followed 
      by high performance liquid chromatography (HPLC) determination. The resultant 
      DMIP was well characterized by FT-IR, SEM, TEM and VSM, exhibiting uniform 
      nanoscale coreshell structure and good magnetic property in favor of simple rapid 
      separation. Several main variables influencing MSPE efficiency were investigated, 
      including DMIP dosage, sample solution pH, extraction time and desorption 
      solvent; central composite design (CCD) and response surface methodology (RSM) 
      were employed to assist in the MSPE condition optimization with rapidity and 
      reliability. Under optimized conditions, excellent linearity for acrylamide was 
      obtained in the range of 5.0-5000.0 microg kg(-1), and low detection and 
      quantification limits were 1.3 microg kg(-1) and 4.4 microg kg(-1), respectively. The 
      method recoveries at five spiked concentrations were found within 86.0-98.3% with 
      relative standard deviations (RSDs) of 1.2-4.1%. Furthermore, endogenous 
      acrylamide was detected in five different biscuit samples and the RSDs values 
      were lower than 3.3%. The present study suggested promising perspectives of 
      water-compatible eco-friendly DMIP based MSPE-HPLC method for highly effective 
      sample pretreatment and targeted analytes determination in complicated matrices.
