The degradation of phenol by electron beam irradiation in aqueous laboratory solutions and also in a real wastewater of steel industry has been investigated. The standard solutions of phenol in the range of 5-22kGy underwent electron irradiation and their concentration before and after the exposure was measured using UV-Vis spectrophotometer, for this purpose absorbance of solution was measured at 460 nm. The concentration of phenol in the effluent before and after irradiation at 10kGy was measured by GC/MS analysis. The effect of experimental parameters like absorbed dose and initial concentration on the efficiency removal was studied. According to the observations, with increasing absorbed doses the removal percentage increases and also by increasing the concentration the amount of removal gradually decreases. In the optimum dose ,10 kGy, the removal percentages of phenol in the standard solution with concentration of 10 mg/L and wastewater of steel industry were 93.5% and 41%, respectively.
