Embodiment 1

[0040] An iron-copper oxide is prepared by heat treatment after reacting potassium ferricyanide solution and cupric chloride solution, specifically comprising 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, stir magnetically for 2 h, and centrifuge to obtain an iron-copper oxide precursor.

[0042] (2) React the iron-copper oxide precursor obtained in step (1) at 550° C. for 2 h to obtain iron-copper oxide, coded as CuFeO.

[0043] An application of the iron-copper oxide in the above-mentioned embodiment in the treatment of antibiotic waste water, specifically utilizing the iron-copper oxide to remove sulfamethazine in water, comprising the following steps:

[0044] Take a sulfamethazine solution with a volume of 1 L and a concentration of 50 mg / L, add 0.5 g of iron-copper oxide and 10 mL of 30% (w / w) H 2 o 2 After mixing the solution evenly, adjust t...

Embodiment 2

[0060] An application of iron-copper oxides in the treatment of antibiotic wastewater, specifically for utilizing iron-copper oxides to remove sulfamethazine in water, comprising the following steps:

[0061] Take 4 parts of sulfamethazine solutions with a volume of 1 L and a concentration of 50 mg / L, add 0.5 g of the iron-copper oxide prepared in Example 1, and then add 10 mL each, with a concentration of 30% (w / w) H 2 o 2 After mixing the solution evenly, adjust the initial pH value of the resulting mixed solution to 4, 6, 8, 10, and perform a Fenton-like reaction under visible light 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 graph showing the removal ef...

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 its preparation method and application. Background technique [0002] Antibiotics are a class of secondary metabolites with anti-pathogen or other activities produced by microorganisms (including bacteria, fungi, actinomycetes) or higher animals and plants in the course of life, which can interfere with the developmental functions of other living cells chemicals. As early as the 1930s, it was found that sulfonamides could effectively treat hemolytic streptococcal infection and were used as clinical medicines. In 1939, the scientist Gerhard Domagk won the Nobel Prize in Medicine for his discovery of the inhibitory effect of Prontosil on Streptococcus. By 1945, more than 5,400 sulfonamides had been synthesized, among which more than 20 were commonly used in clinical practice, such as sulfacetamide, sulfapyridine, sulfathiazole, and sulfamidine. Sulfo...
