Melamine (1,3,5-triazine-2,4,6-triamine), a kind of triazine analogue with three amino groups, is an industrial chemical used in the production of melamine-formaldehyde resins.Because of the substantial amount of nitrogen (66% by mass), it has been used as a filler for protein-rich diets by unethical manufacturers.Therefore, a sensitive and reliable method is urgently needed for the determination of melamine in milk.Molecularly imprinted polymers (MIPs) can selectively adsorb a particular analyte or a group of analytes, which have been recognized as promising and innovative materials.In this study, highly selective MIPs were synthesized by precipitation polymerization using melamine as the template.The results indicated that the imprinting factors (Ⅰ) of melamine and its structural analogue (cyanuric acid and cyromazine) were 7.53, 1.17, 1.56, respectively, which showed that MIPs had a high selectivity and affinity for melamine.Furthermore, the performance of MIPs as solid-phase extraction sorbents was evaluated and high extraction efficiency of molecularly imprinted solid-phase extraction (MISPE) procedure was demonstrated.
