Background: Furfural is an organic compound which derived from a variety industrial, including petrochemicals, pulping, pharmaceutical, food. Also is a main agent in many industries and aromatic organic compounds entrance in the environment. There are several methods of treating including physical, chemical, biological and physicochemical for remove this matter. Among advanced oxidation methods can be combined ozonation process with persulfate catalytic are noted. The purpose of this study was to evaluate the efficiency of ozonation process with the use of persulfate in removal furfural from aqueous solution.

Materials and Methods: In this study, the efficiency of the process with a concentration furfural 5 to 30 mg/L, concentration persulfate 4 to 15 mM, pH = 3-11 and reaction time of 35 minutes in the semi-continuous reactor with a capacity of one liter was obtained.

Results: The results of this study have been shown in  conditions of operation optimal , pH =,3 persulfate dosage 12 mM, ozone dosage of 1 g/min and the initial concentration of furfural  5 mg/L, this process is capable  remove of %93/34 percent Furfural and %70 of the initial COD.

Conclusion: The results of this study showed that the ozone/persulfate process can be a suitable process for the removal of organic aromatic compounds including pollutants of interest.

Keywords: Furfural, O3, Persulfate, Aqueous solutions
