Abstract: An embodiment provides a method for measuring at least one characteristic of an aqueous sample, including: introducing an aqueous sample into a measurement device comprising one or more electrodes; oxidizing a transition metal to produce a higher valent metal by applying an electrical potential between an anode and a cathode of the measurement device; oxidizing, using the higher valent metal as a catalyst, a material within the aqueous sample; measuring a characteristic of the aqueous sample based upon the oxidized material, using a measurement device selected from the group consisting of: an electrochemical measurement device and an optical measurement device; and optimizing the electrical potential and at least one reagent delivered to the measurement device based on the measurement of the characteristic. Other aspects are described and claimed.
