Abstract

The invention discloses a preparation method and application of an oxygen-potential-deficiency magnetic copper ferrite catalyst. The preparation method comprises the following steps: (1) dissolving copper nitrate and iron nitrate into de-ionized water at the mol ratio of 1 to 2 and adding a certain amount of sodium citrate; (2) magnetically stirring the material obtained by the step (1) in an oil bath; (3) taking out the material obtained by the step (2) and drying to form sol; (4) calcining the sol obtained by the step (3) in a muffle furnace to obtain a first component; (5) reducing the first component in a hydrogen atmosphere to obtain the oxygen-potential-deficiency magnetic copper ferrite catalyst. The oxygen-potential-deficiency magnetic copper ferrite catalyst prepared by the preparation method can be used for effectively catalyzing persulfate and the catalyst is magnetic and can be used again after being magnetically separated.

Description

technical field

[0001] The invention belongs to the technical field of catalysts, and in particular relates to a preparation method and application of an oxygen-deficient copper ferrite catalyst. Background technique

[0002] Oxidation method, as an important component in the treatment of wastewater containing organic matter, can effectively remove organic matter that is difficult to biodegrade. Fenton and Fenton-like reactions are widely used in chemical oxidation methods. The advantage is that the generated hydroxyl radicals have strong oxidizing properties, and can oxidize most organic substances indiscriminately to achieve the purpose of removing pollutants. However, due to its relatively harsh requirements on reaction conditions (pH value is about 3), H 2 o 2 The price is expensive, the storage is difficult, and the subsequent biochemical treatment needs to adjust the pH of the influent water, resulting in high treatment costs.

[0003] Based on the sulfate radical (...
