Embodiment 1

[0040] An iron-copper oxide is prepared by reacting potassium ferricyanide solution and copper chloride solution through heat treatment, which specifically includes the following steps:

[0041] (1) Mix 1 L of potassium ferricyanide solution with a concentration of 20 mM and 1 L of copper chloride solution with a concentration of 40 mM, magnetically stir for 2 hours, and centrifuge to obtain the iron-copper oxide precursor.

[0042] (2) The iron-copper oxide precursor obtained in step (1) was reacted at 550° C. for 2 hours to obtain iron-copper oxide, numbered as CuFeO.

[0043] An application of the iron-copper oxide in this embodiment in the treatment of antibiotic wastewater, specifically the use of iron-copper oxide to remove sulfamethazine in water, includes the following steps:

[0044] Take the sulfamethazine solution with a volume of 1L and a concentration of 50mg / L, add 0.5g of iron copper oxide and 10mL of a 30% (w / w) concentration of H 2 O 2 After the solution is uniformly m...

Embodiment 2

[0060] An application of iron-copper oxide in the treatment of antibiotic wastewater, specifically the use of iron-copper oxide to remove sulfamethazine in water, includes the following steps:

[0061] Take 4 parts of sulfamethazine solution with a volume of 1L and a concentration of 50mg / L, add 0.5g of the iron-copper oxide prepared in Example 1, and then add 10mL each with a concentration of 30% (w / w) H 2 O 2 After the solution is uniformly mixed, the initial pH of the obtained mixed solution is adjusted to 4, 6, 8, 10, and the Fenton-like reaction is performed under visible light illumination to complete the degradation of sulfamethazine.

[0062] After the Fenton-like reaction was carried out for 5min, 10min, 15min, 20min, 25min and 30min, samples were taken from the reaction system, and the content of sulfamethazine in the solution was detected by high performance liquid chromatography. The measurement results are shown in Image 6 . Image 6 It is a diagram showing the remov...

Abstract

The invention discloses an iron-copper oxide and its preparation method and application. The iron-copper oxide is prepared by heat treatment after reacting a potassium ferricyanide solution and a copper ion solution. The iron-copper oxide of the present invention has the advantages of large specific surface area, many catalytic sites, high catalytic efficiency, etc., has good magnetism, is easy to separate and reuse, and also has the advantages of low preparation cost, environmental protection, etc., and its preparation method has raw materials It has the advantages of wide source, low production cost, simple preparation process, easy operation, low energy consumption, no toxic and harmful substances, and environmental friendliness. The iron-copper oxide of the present invention can be used as a catalyst for a Fenton-like reaction and can be used to treat antibiotic wastewater. It has the advantages of simple operation, low cost, high treatment efficiency, good treatment effect, low dosage of chemicals, environmental protection, etc., and at the same time It can avoid the shortcomings of iron precipitation caused by the traditional Fenton oxidation method and has good application prospects.

Description

Technical field [0001] The invention belongs to the field of environmental treatment, and relates to an iron-copper oxide and a preparation method and application thereof. Background technique [0002] Antibiotics are secondary metabolites produced by microorganisms (including bacteria, fungi, and actinomycetes) or higher animals and plants during their lives that have anti-pathogen or other activities, which can interfere with the development of other living cells. Chemical substances. As early as the 1930s, people discovered that sulfa drugs can effectively treat hemolytic streptococcal infections and were used as clinical treatment drugs. In 1939, scientist Gerhard Domagk won the Nobel Prize in Medicine for his discovery of the inhibitory effect of Bailangduoxin on Streptococcus. By 1945, more than 5,400 sulfa drugs had been synthesized, of which more than 20 types were commonly found in clinical practice, such as sulfacetamide, sulfapyridine, sulfathiazole and sulfamidine. ...
