Abstract: An embodiment provides a method for measuring total oxidant in a seawater sample, comprising: forming a seawater solution and a formed iodine by introducing a buffer and an iodide reagent to a seawater sample, wherein the seawater sample contains an amount of oxidant; placing the seawater solution in a measurement device, wherein the measurement device comprises a boron doped diamond working electrode reacting with the seawater solution and the formed iodine, wherein an electrochemical process reduces the formed iodine to iodide; and measuring the amount of total oxidant in the seawater sample by measuring, using the measurement device, an amount of iodide in the seawater sample. Other aspects are described and claimed.
