Abstract

The superparamagnetic surface molecularly imprinted Fe₃O ₄@MIP nanoparticles for bisphenol A (BPA) were prepared via surface initiated atom transfer radical polymerization (si-ATRP). The Fe ₃O₄ core was compactly encapsulated with a polychloromethylstyrene (PCMS) layer via mini-emulsion polymerization. Fe ₃O₄@MIP exhibited superparamagnetic property with saturation magnetization of 25.2 emu g^-1. The BPA imprinted Fe ₃O₄@MIP revealed specific selectivity and high affinity to the template BPA over structural analogues. Moreover, the surface-imprinted MIP nanoparticles showed good site accessibility for BPA. The compactly PCMS-coated Fe₃O₄@MIP maintained its response ability to a magnetic field at acidic and alkaline conditions. Fe₃O₄@MIP was used to determine BPA in tap water samples with good accuracy and precision.
