Mineralization of organic pollutants in the water utilizing photo-assisted Fenton reaction and ferrite catalysts

在这项研究中，使用铁氧体固体催化剂结合紫外线照射的方法进行了研究，以抑制氢氧化铁污泥的产生，促进矿化的废水处理。磁性分离可用于从水中去除铁氧体催化剂。在酸性条件下，苯酚在催化剂的存在下被降解，然而，这是由于从催化剂上洗脱的铁离子。为了抑制铁离子的洗脱，在中性pH下进行处理。在使用125 mg/L的Cu-铁氧体催化剂的情况下，超过90%的100 mg/L的苯酚可以在3 h内矿化与高压汞照射。

In this study, the method using a ferrite solid catalyst combined with UV irradiation is examined for wastewater treatment in order to suppress the generation of iron hydroxide sludge and to promote mineralization. Magnetic separation can be utilized for removing ferrite catalysts from water. Phenol was degraded in the presence of a catalyst in the acidic condition, however, it was due to the iron ions eluted from catalysts. In order to suppress the elution of iron ion, the treatment was performed at neutral pH. In the case of using a Cu-ferrite catalyst at 125 mg/L, more than 90% of phenol of 100 mg/L could be mineralized in 3h with a high pressure mercury irradiation.
