Title in original language:Effect of binding constants on the extraction of herbicides with cyclodextrin polymers
Keywords:cyclodextrin polymers, binding constants, extraction
Subject:Nanociència
Abstract:Binding constants of inclusion complexes between α, β and γ cyclodextrins with 4-chlorophenoxyacetic acid, 2,4-dichlorophenoxyacetic acid and 2,4,5-trichlorophenoxyacetic acid, were determined using ultraviolet-visible spectroscopy. Linear and nonlinear regression methods were employed. Relationship with the removal efficiencies of β and γ cyclodextrin-based polymers containing hexamethylene diisocyanate (HDI) and epichlorohydrin (EPI) was evaluated using HDI and EPI maltodextrin polymers as controls. Dependence on the cyclodextrin cavity size and the polarity of the herbicide molecules is suggested. Relationship with the removal efficiencies demonstrate primary adsorption mechanism involved could be formation of inclusion complex, although effect of other adsorption mechanisms is not ruled out.
