Molecularly imprinted polymers (MIPs) have aroused extensive attention and been widely applied in many fields, such as solid phase extraction and chemical sensors, owing to their desired selectivity, physical robustness, thermal stability, as well as low cost and easy preparation.While MIPs enjoy some advantages mentioned above, its also involved in many problems such as incomplete template removal, low binding capacity and slow mass transfer because of highly cross-linked nature.In order to overcome those problems, three kinds of new MIPs were prepared based on reversible addition-fragmentation chain transfer polymerization, surface imprinting technique and porous polymer preparation method.All the three kinds of MIPs display higher binding capacity and fast mass transfer than those MIPs prepared by commonly used bulk polymerization.The obtained MIPs were successfully applied as solid phase extraction sorbent for high selective preconcentration and determination of triazines in com, lettuce and soil samples.
