A simple and sensitive fluorophotometric method for the determination of resorcinols was examined utilizing a condencation reaction with 2,4-dihydroxybenzo-ylbenzoic acid in the precence of H4P2O7. In the determination of resorcinol, the calibration curve exhibited linearity over a resorcinol concentration range of 1.0~ 1100 ng mL-1 at an emission wavelength of 515 nm with an excitation of 445 nm and with the relative standard deviations (n=5) of 4.8% for 110 ng mL-1 of resorcinol.
