摘要: Abstract The interaction between sulphonated monoazo dyes and poly(vinylpyrrolidone) in the presence of bolaform electrolytes with two quaternized amino groups was investigated by means visible absorption spectrum measurements. first binding constants poly(vinylpyrrolidone), determined neglecting electrolytes, were much larger than those absence electrolytes. However, aqueous solutions found, so that above assumption not fulfilled. Therefore, dye/bolaform electrolyte complexes using equation based on equilibria trinary systems containing dyes, poly (vinylpyrrolidone). (vinylpyrrolidone) which suggests enhance affinity for polymer through formation complexes.
