A set of physicochemical methods was used to study supramolecular interactions in an aqueous system based on the anionic surfactant SDS, oxime 2-PAM and macrocycle β-CD. The nature of the interactions between these components both in monomeric and aggregated forms was revealed. The kinetics of the reaction of paraoxon hydrolysis in the solutions was studied spectrophotometrically. It was found that the catalytic effect in this reaction increases in the aqueous medium if the supramolecular β-CD–SDS–2-PAM system is in the form of micellar aggregates.
