Abstract

The invention provides a core-shell-structured hierarchical iron / copper bimetallic Fenton catalyst and a preparation method and application thereof, belonging to the technical field of degradation treatment of organic pollutants in wastewater in virtue of Fenton catalysts. The preparation method comprises the following steps: adding zeolite into a ferric iron salt solution, carrying out stirring for a reaction, then carrying out centrifugal washing with deionized water, and performing freeze drying to obtain an isolated iron catalyst; and then adding the obtained isolated iron catalyst into abivalent copper salt solution, carrying out a stirring reaction for a certain period of time, then carrying out centrifugal washing with deionized water, and carrying out freeze drying to obtain the core-shell-structured hierarchical iron / copper bimetallic Fenton catalyst. The catalyst prepared in the invention has a wide pH application range, can be used for Fenton oxidation degradation of organic pollutants in high-pH environmental sewage and has excellent catalytic performance and reusability; and an effective method for is provided for the application of the bimetallic Fenton catalyst anddegradation treatment of sewage.

Description

technical field

[0001] The invention belongs to the technical field of Fenton catalysts for degrading and treating organic pollutants in wastewater, and in particular relates to a core-shell graded iron / copper bimetallic Fenton catalyst and its preparation method and application. Background technique

[0002] In recent years, the protection of water resources has become one of the serious issues affecting people's quality of life and ensuring sustainable development of the environment. Among various sewage treatment methods, the Fenton method is widely used in wastewater treatment, especially in the process of biodegradable sewage treatment, because of its rapid degradation rate, low toxicity, simple operation, non-toxic effect on subsequent treatment, and environmental friendliness. received widespread attention.

[0003] The traditional Fenton reaction mechanism leads to relatively harsh reaction conditions and high requirements for the acidity of the reaction. Usually, ...
