Description
Technical field
The present invention relates to it is a kind of exempt from processing can repeatedly use tetracycline degradation photochemical catalyst preparation method and its
Using belonging to pollutant control field.
Background technique
Antibiotic is made that huge tribute as one of greatest discovery of the twentieth century mankind, for clinical medical development
It offers, has saved the life of countless sufferers.However, at present abuse of antibiotics problem also than more prominent or even many antibiotic by with
In the growth (asian treatment dosage) for promoting animal.The metabolic rate of antibiotic in vivo is lower, it was found that there are about the anti-of 30-90%
Raw element is discharged with prototype by excreta.The phenomenon that abuse of antibiotics, results in many antibiotic to be discharged into environment.And
The antibiotic overwhelming majority for being discharged into environment finally can all enter water environment, therefore the influence to water environment is the most serious.Antibiotic
Harm maximum to environment is that bacterium can be caused to generate drug resistance, causes to generate the drug-fast bacteria to past medical help.Therefore, it reduces anti-
Raw element pollution is significant.
Photocatalysis technology is as a kind of green catalysis technology, and the application in terms of environmental contaminants improvement is increasingly by weight
Depending on.It has many advantages, such as that green, pollution-free, energy consumption is few using natural light as the driving force of catalysis.Tetracycline is a kind of wide spectrum
Antibiotic has been widely used for the disease treatment of people, animal, and annual usage amount is huge, residual in the environment also compared with
It is more, have become a threat for influencing Environmental security.There is researcher to start using photocatalyst for degrading tetracycline.But mesh
That when degrading tetracycline, there is also degradation times is long for preceding photochemical catalyst, reduces the lower problem of efficiency.As prepared by Yang Chen et al.
TiO2/ GO composite photo-catalyst, illumination 90min reach a kind of most degradation rate~65% [efficient degradation tetracycline to tetracycline
Composite photo-catalyst and the preparation method and application thereof, grant number ZL201510278124.0]；Apply big east et al. preparation
Bi4V2O11/RGO photochemical catalyst, illumination 60min, reaching most degradation rate~70% to tetracycline, [a kind of hetero-junctions for preparing is multiple
The method of light combination catalyst, number of patent application 201711127019.2].In addition, when photochemical catalyst regenerates, it is often necessary to use H2O2
Or other reagents progress regeneration treatments could put into the Catalysis work [201711127019.2] of next round.These deficiencies all influence
Photochemical catalyst on a large scale promotes and applies in processing pollutant field.
Based on background above, this technology has invented a kind of tetracycline degradation photochemical catalyst exempting from processing and can repeatedly using
Preparation method and applications.The catalysis material BiOBr/rGO prepared using the method, the degradable tetracycline of illumination 20min
90% or more, illumination 130min or so basically reach catalytic equilibration, and degradable tetracycline 99% is shown quickly high to tetracycline
The degradation property of effect.In addition, used catalyst need to only be separated from the water body for reached catalytic equilibration, it is not required to be appointed
What regeneration treatment (including not needing to be rinsed with water) can put into the new waste water to be processed containing tetracycline and carry out next round
Catalysis work is at least reused 4 times, and catalytic activity is not substantially reduced.The catalyst, degradation tetracycline speed is fast, efficiency
It is high, to exempt from regeneration treatment, reusability good, can preferably solve some passes that current photocatalyst for degrading tetracycline is encountered
Key problem may advantageously facilitate the development of photocatalyst for degrading antibiotic.This technology correlation technique has not been reported.
Summary of the invention
The purpose of the present invention is to provide a kind of systems for exempting from the tetracycline degradation photochemical catalyst that processing can repeatedly use
Preparation Method and its application.
The present invention uses following means: a kind of preparation for exempting from the tetracycline degradation photochemical catalyst that processing can repeatedly use
Method and its application, it is characterised in that method and steps is as follows:
(1) positive six alcohol of 10mL is dispersed by the GO of 1.4mg-20mg, is solution A；
(2) by 0.6mmol Bi (NO3)3·5H2O is dissolved in positive six alcohol of 20mL, is B solution；
(3) 0.6mmolCTAB (cetyl trimethylammonium bromide) is dissolved in positive six alcohol of 20mL, is C solution；
(4) A, B, C solution are mixed and 0.1g-0.3g glucose and 5mL ethylene glycol is added after ten minutes, and ultrasound 30
Continue stirring 1 hour after minute.It is then transferred in reaction kettle, 180 DEG C are reacted 24 hours.It after reaction, is cooled to room temperature, will consolidate
Body is separated, and is alternately cleaned up with ethyl alcohol and deionized water, material is freeze-dried up to product.
(4) the product BiOBr/rGO composite photocatalyst material prepared by, visible light absorbing quickly and efficiently drop by photocatalysis
Tetracycline is solved, and after product reaches catalytic equilibration for photocatalytic degradation tetracycline, product is separated from processed water body, it can
It is without any processing and put into new need processing water body and carry out next round Catalysis work, it at least can so reuse 4 activity
Nothing is decreased obviously.
The present invention has the advantages that 1. can utilize Visible Light Induced Photocatalytic tetracycline, the time of degradation is short, high-efficient；2. when place
When reason waste water has reached catalytic equilibration, need to only come out the photocatalyst separation can be direct plungeed into the waste water of new need processing
It uses, does not need to do any regeneration treatment；3. the catalyst repeat performance is good, at least reusable 4 times and it is active
Nothing is decreased obviously；4. material preparation method is simple, low in cost, there are the potentiality of large-scale promotion application.
