摘要: Abstract The behaviour of the pyrene (Py), 8-anilino-1-napthalenesulfonic acid ammonium salt (ANS) and Pyronin Y (PyY) in Tween series polyoxyethylene nonionic surfactants contained aqueous solutions was investigated using fluorescence spectroscopic technique. object investigations were interactions between given dye surfactant a wide range concentrations temperature from 293 to 318 K. obtained spectra basis for determination critical micelle (CMC) surfactants, thermodynamic analysis dye-surfactant binding process correlation with micropolarity microviscosity environment. parameters changes concentration also studied intermolecular solution surfactant.
