Komorsky-Lovric S: Kinetics of the alizarine red S surface redox reaction. Anal Bioanal Chem. 1996 Sep;356(3-4):306-9.
Kinetics of the surface redox reaction of alizarine red S adsorbed on mercury is measured by square-wave voltammetry. In 1 mol/l KNO (3) buffered to pH 9.22, the standard reaction rate constant of the redox couple anthraquinone/anthrahydroquinone in the adsorbed alizarine red S molecule is k (s)=100 +/-10 s (-1) and the cathodic transfer coefficient is alpha=0.4. At pH 2 in this medium k (s) is greater than 500 s (-1). |
