Use of a manganese dioxide column in the flow enthalpimetric determination of hydrogen peroxide.
A method for flow enthalpimetric determination of H(2)O(2) is described. The method uses manganese dioxide to catalyse the decomposition of H(2)O(2). The catalyst is stable enough to be used for at least 500 analyses. H(2)O(2) in the concentration range 0.01-10mM is determined with coefficients of variation < 2%. The method has been used for determination of glucose in a non-alcoholic beverage and wines, with glucose oxidase as the peroxide-producing enzyme.
