Abstract: A novel reproducible solid-phase microextraction (SPME) coating was prepared on the surface of silanized silica fibers by molecularly imprinted polymerization using prometryn as template molecule. The structure and extraction performance of molecularly imprinted polymer (MIP) coating was studied with the scanning electron microscope and high performance liquid chromatography (HPLC). Specific selectivity was found with the prometryn MIP-coated fiber to prometry and its structural analogues such as atrazine, simetryn, terbutylazin, ametryn, propazine and terbutryn. In contrast, these triazines could not be selectively extracted by the nonimprinted polymer fiber or commercial polydimethylsiloxane (PDMS), polydimethylsiloxane/ divinylbenzene (PDMS/DVB), polyacrylate (PA) fibers
Template and target information: prometryn
