Abstract

Nanosized NiFe₂O₄ has been obtained using solution combustion synthesis (SCS). The predominant fraction of the particles has a size of 21–50 nm (TEM). The degree of degradation of 2,4-dinitrophenol in a Fenton-like reaction in the absence of the NiFe₂O₄ catalyst is 6%, and that in the presence of NiFe₂O₄ is 53%. Effective oxidative degradation of the pollutant was carried out in a less acidic medium and at a higher initial concentration of dinitrophenol in comparison with the classical Fenton process. The results of the study can be applied in the development of new environmentally friendly water treatment systems at enterprises that use organic dyes in production cycles.

研究铁氧体镍对 2,4-Dinitrophenol 的吸附和催化特性

摘要利用溶液燃烧合成法（SCS）获得了纳米化的 NiFe2O4。主要颗粒的尺寸为 21-50 纳米（TEM）。在没有 NiFe2O4 催化剂的情况下，2,4-二硝基苯酚在类似芬顿反应中的降解率为 6%，而在有 NiFe2O4 的情况下为 53%。与经典的 Fenton 过程相比，在酸性较低的介质中和较高的二硝基酚初始浓度下，污染物都能得到有效的氧化降解。研究结果可用于在生产循环中使用有机染料的企业开发新的环保型水处理系统。
