Abstract: The chemiluminescence (CL) generated from the hydrogen peroxide oxided by periodate could be enhanced differently by polyhydrophenols, such as pyrogallol, phloroglucinol, pyrocatechol, resorcinol and parodioxybenzene. Furthermore, the CL could be improved in the presence of the trace non-polar organic solvent, the possible mechanism was proposed. Based on which a sensitive CL method for polyhydrophenols has been built. The linear ranges of determination for pyrogallol, phloroglucinol, pyrocatechol, resorcinol and parodioxybenzene were 1×10-5～2×10-7mol/L, 1×10-3～1×10-5mol/L, 1×10-4～6×10-6mol/L, 1×10-3～2×10-5mol/L and 1×10-3～6×10-5 mol/L, respectively, and their detection limits were 7.2×10-8mol/L, 6.8×10-6 mol/L, 2.1×10-6mol/L , 7.1×10-6mol/L and 2.2×10-5mol/L respectively.
