Sulfur was recovered from hydroxyl iron oxide desulfurizer containing 25.0% sulfur by solvent method in tetrachloroethylene solvent. The influence of reaction temperature,reaction time,liquid-solid ratio and reusing times of organic solution on sulfur recovery was investigated. The hydroxyl iron oxide desulfurizer and the product were characterized by X-ray diffraction (XRD) technology. The results show that, when the liquid-solid ratio of tetrachloroethylene to desulfurizer hydroxyl iron oxide containing 25.0% sulfur is 8:1, leaching temperature is 80 ℃, leaching time is 60 min, hydroxyl iron oxide is 20 g, the recovery of sulfur can be over 97.5%. The XRD characterization result has proved that recovered product is sulfur.
