Detection of oxidant in seawater

A measurement device for measuring total oxidant in a seawater sample, comprising:

• at least one measurement chamber;
• a processor;
• and
• a memory storing instructions executable by the processor to:
• form 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;
• place 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
• measure the amount of total oxidant in the seawater sample by measuring, using the measurement device, an amount of iodide in the seawater sample.
