A derivatization technique has been developed for the combined determination of hydrogen peroxide and some organic hydroperoxides in precipitation samples. A fluorescent dimer is formed via the reaction of peroxides with p-hydroxyphenylacetic acid and horseradish peroxidase. The resulting dimer is stable for a minimum of 5 days, eliminating difficulties caused by the decomposition of peroxides in stored samples. The detection limit is 3 x 10/sup -8/ M, based on 3 times the standard deviation of the blank. 6 references, 1 figure, 3 tables.
