Amperometric-non-enzymatic method of determining sugars and other polyhydroxy compounds
First Claim
1. A method for determination of hydrogen peroxide, sugars and other polyhydroxy compounds comprising providing the compound in an aqueous alkaline solution, applying a constant potential between a transition metal oxide catalyst electrode and a counter electrode immersed in the solution whereby electrocatalytic oxidation of the hydroxy compound occurs at the surface of the transition metal oxide electrode, and measuring the rise in current from the electrochemical oxidation.
