Abstract

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