The dimerization of (p-hydroxyphenyl)acetic acid by hydrogen peroxide in the presence of peroxidase has been adapted to the determination of hydrogen peroxide in seawater. The fluorometric method presented requires only one mixed reagent for sample analysis and produces a stable product that does not require immediate measurement. Changes in reaction stoichiometry resulting from naturally occurring organic material have been addressed. The detection limit, defined as 3 times the standard deviation of the blank, is 4 and 4 nM for open ocean and coastal seawater, respectively.
