FeOOH催化降解苯酚的性能研究

用沉淀法制备FeOOH,以此为催化剂采用非均相Fenton高级氧化技术降解苯酚。对催化剂的投加量、H2O2的投加量、初始pH对苯酚去除的影响进行了实验研究。结果表明,pH=3.0、双氧水的投加量为19.6mmol·L-1,催化剂的投加量为2.0 g·L-1,室温下反应10 min,苯酚的去除率可达90%以上。非均相Fenton氧化法降解苯酚能有效拓宽反应溶液pH值范围,对废水的苯酚的去除具有广阔的应用前景。

Catalytic and Degradation Characteristics of FeOOH on Phenol

The FeOOH were synthesized by distributed precipitation method and was used as the catalyst of heterogeneous fenton oxidation to degrade phenol. The dosage of FeOOH, the concentration of H2O2 , and the pH of solution on the degradation of phenol were investigated. The study results demonstrated that the degradation efficiency of phenol reached 90% after 10 min under the condition of 19.6 mmol/L H2O2 , pH = 3.0 and 2. 0 g/L FeOOH at room temperature. Fenton oxidation degradation of phenol can effectively broaden the pH range of the reaction solution. It has wide application prospect to removal of phenol in wastewater by fenton technology.
