Preparation of magnetic superhydrophilic molecularly imprinted resins for detection of triazines in aqueous samples
چکیده انگلیسی


- Fe3O4@NH2 were first introduced to prepare magnetic superhydrophilic molecular imprinted resins (MMIRs).
- Preparation method was based on one-pot condensation of resorcinol, melamine and formaldehyde.
- Product yield is higher.
- Preparation and extraction process are simple, efficient and fast.
- Application of MMIRs for the determination of triazines in aqueous samples combined HPLC-MS/MS.

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 0.02-0.07 μg L−1 (except for simazine, 0.38 μg L−1). At the spiked level (5 μg L−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.
