Perchloric acid enhances sensitivity and reproducibility of the ferric-xylenol orange peroxide assay.
TL;DR: The ferrous oxidation in xylenol orange (FOX) assay for hydroperoxides suffers from very narrow pH optimum in the range 1.7-1.8, and substitution of perchloric for the sulfuric acid resulted in a lowering of the optimum pH of the assay to 1.1, a decreased dependence of the absorbance of the ferric-xylenl orange complex on acid concentration and decreased sensitivity to added compounds.
