Selective separation of deltamethrin by molecularly imprinted polymers using a β-cyclodextrin derivative as the functional monomer.
    Journal of environmental science and health. Part. B, Pesticides, food contaminants, and agricultural wastes, 2013, Volume: 48, Issue:5

    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 (ΔC(P)) 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.

Chiral separation of pyrethroic acids with single isomer permethyl monoamino beta-cyclodextrin selector.
    Electrophoresis, 2001, Volume: 22, Issue:15

    Enantiomers and diastereomers of chrysanthemic, permethrinic, and deltamethrinic pyrethroic acids were separated from each other, using positively ionizable permethyl monoamino beta-cyclodextrin (PMMAbetaCD). The highest chiral resolution value was 20.0. The optimum conditions of separation were found to be 16 mM PMMAbetaCD concentration and pH 6.5, where analytes and selector were in oppositely ionized states. Selectivity of PMMAbetaCD proved to be the best among the cyclodextrin derivatives studied.
