Spectrophotometric Investigation of the Formation of Association Complexes between Alizarin Red S and β-Cyclodextrin

The acid-base equilibria of Alizarin Red S(ARS) were investigated spectrophotometrically at 25 °C and μ=0.2 in the presence of β-cyclodextrin (β-CD). In the presence of β-CD, the dissociation of the first proton (β-OH) of ARS is slightly enhanced and that of the second one (α-OH) is significantly su...
