Determination of organic carbon in water with a silver-catalyzed peroxydisulfate wet chemical oxidation method

The application of Ag(I) catalysis of S₂O₈^2? to the oxidation of organic carbon to CO₂ for determination of dissolved organic carbon in aqueous samples is described. The resulting method combines to a significant degree the speed of high-temperature combustion methods and the sensitivity of wet chemical oxidation. For some samples, a higher oxidation efficiency has been observed than with an uncatalyzed wet chemical oxidation method.
