The effect of cetyltrimethylammonium bromide on the inhibition of the oxidation of fluorescein by potassium bromate was studied. The sensitization kinetic spectrophotometric method for the determination of trace phenols was proposed. After the addition of cetyltrimethylammonium bromide, the maximum absorption wavelength of the system was red shifted from 440 nm to 540 nm, and the sensitivity was significantly improved. The concentration of phenol in the range of 0.5-50 ug / L showed a linear relationship with A. The mechanism of kinetic reaction was discussed. The reaction was confirmed as a series of reactions. The proposed method was applied to the determination of trace phenols in environmental water samples.
