Abstract: Molecularly imprinted silica nanospheres with special molecule recognition properties for bisphenol A (BPA) were prepared with a sol-gel process using bisphenol A as a template molecule, and aminopropyltriethoxysilane (APTES) as a functional monomer. The BPA-imprinted silica nanospheres, as the solid-phase extraction (SPE) sorbents, the SPE conditions were optimized, and dichloromethane was selected as the loading solvent. The selective extraction of BPA from BPA and its three structural analogues BPC, TBBPA and NP showed that the BPA-imprinted silica nanoparticles SPE column had much higher selectivity for BPA with recoveries of 90.7%. The canned food samples spiked at two concentration levels of 2.5 and 5 μmol/L BPA were prepared by SPE column and determined by HPLC with recoverey of 72%~84% and relative standard deviations (n = 3) of 2.9% ~ 4.4%.
