Abstract
The acidity constants of Alizarine Red S in water, water-Brij-35 and water-SDSÂ micellar media origins at 25 degrees C and an bean strength of 0.1 M have been determined spectrophotometrically. To evaluate the pH-absorbance data, a resolution method based on the combination of soft- and hard-modeling is applied.
The acidity constants of all related equilibria are estimated using the whole unearthly fitting of the collected data to an established factor abbreviation model. DATAN program applied for determination of acidity constants. Results show that the pKa determine of Alizarine Red S are influenced as the percentages of a neutral and an anionic surfactant such as Brij-35 and SDS, respectively, added to the solution of this reagent. Effect of surfactant on acidity constants and pure spectrum of each(prenominal) component are also discussed.
