title: Preparation of magnetic superhydrophilic molecularly imprinted resins for detection of triazines in aqueous samples.
abstract: In this work, magnetic superhydrophilic molecularly imprinted resins (MMIRs) were prepared for the determination of triazines in aqueous samples combined HPLC-MS/MS. The amino functionalized magnetic nanoparticles were introduced into superhydrophilic molecularly imprinted resins based on one-pot condensation of resorcinol, melamine and formaldehyde. The obtained MMIRs exhibited magnetic responsiveness, superhydrophilic and selective feature. The MMIRs were directly used as adsorbents for selective enrichment and separation of six triazines in juice and lake samples under an applied magnetic field. The detection limits of triazines are in the range of 0.02-0.07μgL-1(except for simazine, 0.38μgL-1). At the spiked level (5μgL-1), the recoveries are in the range of 85-101% with the RSDs ≤7%. This work provided a novel and efficient approach for the detection of triazines in aqueous samples.
