摘要

摘要研究了低成本催化剂在亚甲基蓝脱除废水中的应用。非均相Fenton-like工艺包括使用双氧水溶液和富铁催化剂,红泥和黑镍泥用于该目的。对催化剂用量、过氧化氢溶液体积等因素进行了监测。实验结果表明,所选催化剂在类芬顿氧化过程中对亚甲基蓝染料的降解可以用拟二级动力学模型来描述。反应30 min后,黑镍泥催化剂的染料去除率最高,达到87.15%。

Heterogeneous Fenton-Like Oxidation of Methylene Blue Using Alternative Catalysts
Abstract The usage of the low-cost catalysts for methylene blue removal from wastewater was investigated. Heterogeneous Fenton-like process consists of the use of a hydrogen peroxide solution, and an iron-rich catalyst, red mud and black nickel mud were used for that purpose. The factors such as the catalyst dose and the hydrogen peroxide solution volume were monitored. The results of experiments showed that the degradation of methylene blue dye in Fenton-like oxidation process using selected catalysts can be described by a pseudo-second-order kinetic model. The highest dye removal efficiency (87.15 %) was achieved using the black nickel mud catalyst after 30 minutes of reaction.
