Description
Binding of Methyl, Ethyl and Butyl Oranges (MO, EO and BO) to poly (N-butyl-4-vinylpyridinium bromide) (C4P 4 VP) (Degree of Quaternization, DQ= 100%) has been studied at 25°C by means of the dynamic dialysis technique and spectrophotometry. The binding isotherms for MO, EO and BO-C4P 4 VP in an acetate buffer solution at pH 5.7 show the high binding affinities with the binding densities close to 1 over ten fold variation of the dye concentrations (Figs.2, 3 and 4). In terms of the theory of Bradley et al., the change of absorption spectra of MO, EO and BO-C4P 4 VP (Figs.6, 8 and 9) reveals that the stacking coefficient q, which represents the interaction between -neighbouring dyes bound to polymer sites, increases in the order, MO<EO<B0 (Table 1).
