Abstract
:
The electronic absorption spectra of different acid dyes, Crocein Orange G, Acid Alizarin N and Acid Orange 10 have been investigated in aqueous and non-aqueous solutions. Also spectrophotometric results on the aggregation of the studied dyes in presence of electrolytes are presented. As the concentration of the dye increases the absorption spectra shifts to shorter wavelengths, this behaviour has been attributed to the formation of high aggregates. The larger wavelength, almost worked in dilute solutions, is typical of the monomeric dye. The aggregation of these dyes was studied quantitatively using the Maximum Slope Method. The investigated three dyes are aggregated at room temperature with an average aggregation number.
