Spectrophotometric Determination of Acidity Constants of Alizarine blushful S in Water, Water-brij-35 and Water-sds Micellar Media Solutions.. Jun 2006;64:660-4 Abstract The moroseness constants of Alizarine ablaze(p) S in water, water-Brij-35 and water-SDS micellar media origins at 25 degrees C and an dome strength of 0.1 M have been regularised spectrophotometrically. To evaluate the pH-absorbance data, a re upshot method based on the combination of soft- and hard-modeling is applied.

The acidity constants of all related equilibria are estimated using the whole eldritch 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 B rij-35 and SDS, respectively, added to the ! solution of this reagent. Effect of surfactant on acidity constants and pure spectrum of each(prenominal) fragment are also discussed.
