摘要

A deltamethrin-imprinted polymer (MIP_1) was prepared using bis(-6-O-butanediacid monoester)-β-cyclodextrin (BBA-β-CD) as the functional monomer and toluene 2,4-diisocyanate (TDI) as the cross-linker. In comparison to the molecularly imprinted polymer where β-CD was applied as the functional monomer (MIP_2), MIP_1 showed a higher specific binding capacity (ACp) and an improved imprinting factor (IF) for deltamethrin. The selective recognition experiments demonstrated that compared to MIP_2, MIP_1 could better recognize its template over other substrates that had similar chemical structures. The solid phase extraction (SPE) of deltamethrin using MIP_1 as the adsorbent was further investigated. The recoveries of the molecularly imprinted solid phase extraction (MISPE) column for deltamethrin were 83.2-93.4% with relative standard deviations (RSD) of 2.03-6.19%. The method has been successfully applied to the enrichment of trace deltamethrin from real water samples.
