Preparation method of iron vanadate loaded cotton fabric

Abstract

The invention relates to a preparation method of an iron vanadate loaded cotton fabric, and belongs to the field of material preparation. The preparation method is characterized by comprising the following steps: wetting a cotton fabric with deionized water, placing the wet cotton fabric in an ethanol-water system, carrying out ultrasonic treatment, taking out the cotton fabric, washing the cottonfabric with deionized water, and drying the cotton fabric for later use; adjusting the pH value in a three-necked flask filled with the ethanol-water system, adding a silane coupling agent, and fullyhydrolyzing the silane coupling agent by ultrasonic treatment; adding iron vanadate powder, and continuously carrying out surface modification on the iron vanadate by ultrasonic treatment; then adjusting the pH value of the system by using a sodium hydroxide solution, putting the three-necked flask into an oil bath, and drying the cotton fabric, which is wetted by deionized water and dried by extruding, under mechanical stirring; and then washing the cotton fabric with water and drying the cotton fabric to obtain the iron vanadate loaded cotton fabric. The silane coupling agent KH560 is usedas an important medium to enable iron vanadate and cotton fabric to be firmly bonded, a novel catalyst namely iron vanadate/cotton fabric is successfully prepared by impregnation, and iron vanadate isuniformly distributed on the surface of the fabric and has good catalytic degradation performance for tetracycline hydrochloride.

Description

technical field [0001] The invention belongs to the field of material preparation, and in particular relates to a method for preparing iron vitrinate-loaded cotton fabrics. Background technique [0002] The total amount of antibiotics used in the world is about 100,000-200,000 tons per year, at least 50% of which are used in animal husbandry and aquaculture. In animal husbandry, because tetracycline has the advantages of broad spectrum, high quality and low price, and can promote the growth of livestock and poultry when added at low doses, and can be used to treat diseases at high doses, it has become a production and Antibiotics used in large quantities in clinical practice. Tetracyclines are used in a variety of infectious diseases, such as respiratory, sinus, otitis media, urinary and intestinal, and can also be used to treat gonorrhea, but because of their side effects, instability in different environments, especially constant exposure to water Accumulation, so that i...

Problems solved by technology

[0003] Traditional photocatalytic research is often carried out in a suspension system. Due to the small size and specific gravity of catalyst particles, traditional separation methods such as filtration, precipitation, flocculation, and centrifugation are difficult to separate, recycle, and regenerate them. At the same time, catalysts It is easy to condense and poison, and cannot realize continuous operation, resulting in a large amount of iron-containing sludge, which will cause secondary pollution to the water body

The ferric vitriol particles suspended in the reaction system will not only absorb and block light during use, but also affect the irradiation depth of the light source

At present, the research on the suspended photocatalytic system is mainly carried out in the laboratory, and it is difficult to achieve large-scale industrial application.
