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 a ferric-copper oxide as well as a preparation method and an application thereof. The ferric-copper oxide is prepared from a potassium ferricyanide solution and a copper ion solution through a reaction and heat treatment. The ferric-copper oxide has the advantages of large specific surface area, multiple catalytic sites, high catalysis efficiency and the like, has better magnetism, is easy to separate and reutilize and also has the advantages of low preparation cost, environmental friendliness and the like. The preparation method of the ferric-copper oxide has the advantages that raw materials are widely sourced, the production cost is low, the preparation process is simple, operation is simple and convenient, the energy consumption is low, no toxic or harmful substances are produced, the preparation method is environmentally friendly and the like. The ferric-copper oxide can serve as a catalyst of a Fenton-like reaction, can be used for treating antibiotic wastewater, has the advantages of being simple and convenient to operate, lower in cost, high in treatment efficiency, good in treatment effect, low in adding dosage of chemical agents, environmentally friendly and the like, the defect that iron precipitates can be produced with a conventional Fenton oxidation method can be overcome, and the ferric-copper oxide 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. ...
