Fe/AC非均相Fenton体系降解BPA

Degradation of BPA by heterogeneous Fenton-like action using active carbon-Fe

采用常规浸渍法制备和超声浸渍法制备活性炭载铁催化剂,作为非均相Fenton反应的催化剂。采用电镜扫描和能谱分析对催化剂的形貌特性进行分析,以双酚A为目标降解物,考察催化剂的降解性能。结果表明,超声浸渍法制备的催化剂,活性组分含量高,在载体表面负载均匀,催化剂性能稳定。催化剂用量为2 g/L,H2O2浓度为0.06 mol/L,p H值为6的条件下,催化降解BPA的效率达90%。

The activated carbon supporting Fe catalysts were prepared for heterogeneous Fenton reaction by impregnation and ultrasonic-assisted impregnation. The catalysts surface morphology was characterized by SEM and EDX. Bisphenol A( BPA) was selected as the target pollutant to study oxidation activity of the prepared catalyst. By comparison,the loaded content of Fe was higher on catalysts prepared by ultrasonic-assisted impregnation,which showed more excellent stability and oxidation capacity. As the result,90% of BPA could be degraded effectively under the optimum conditions: 2 g / L of catalyst,0. 06 mol / L of H2O2 and p H 6.
