Manage the research hotspot of antibiotic residue.Semiconductor light-catalyst material be the key that influence Photocatalytic Degradation Property, exploitation it is novel,
Efficient photocatalyst material is photocatalysis technology practical application urgent problem to be solved, has obtained extensive concern.It uses at present
In the photochemical catalyst of research be mainly n-type metal oxide semiconductor, especially TiO2Because its is nontoxic, stablize and it is cheap due to apply
Must be the most extensive, but since the energy gap of its 3.2eV causes the absorption to sunlight only in ultraviolet light range, and this portion
The light of partial wave length only accounts for 4% or so of sunlight, seriously affects its service efficiency.And conventional Ti O2Powder photocatalyst ratio
Surface area is small, and chemism is low.Molybdenum disulfide is as a kind of stratiform transient metal sulfide, due to its unique layer structure quilt
It is widely used in opto-electronic conversion and photocatalysis field.With TiO2It compares, the band gap width of molybdenum disulfide only has 1.80eV left
The right side, which includes visible light part to sunlight, has very strong absorption, while it has good chemical stability, takes long benefit
Short, molybdenum disulfide equally has prodigious research significance and application potential in photocatalysis field.As patent CN106582880A is public
Having opened molybdenum disulfide/MIL-101 composite photocatalyst materials is preparation method and its is led in degradation antibiotic waste water containing Ciprofloxacin
Application in domain.Relative to traditional powder body material, nano-porous materials have that large specific surface area, dangling bond be abundant, reactivity
Characteristic more than position.It is to be noted that the molybdenum disulfide nano material currently reported, although size is smaller, specific surface area compared with
It is small, and building-up process is complicated, it is less to the efficient improvement application of high concentration antibiotic.
Invention content
The present invention is directed to traditional photochemical catalyst low problem of catalytic efficiency under visible light, provides a kind of mesoporous curing
The preparation method of molybdenum visible light catalyst material and its application in degradation treatment antibiotic waste water field, especially highly concentrated
Spend the application in quadracycline and sulfamethazine antibiotic.It is equal that this method can prepare regular appearance, Size Distribution
Even mesoporous molybdenum disulfide visible light catalyst material, the preparation method is simple, quick and easy to operation, and the light being prepared is urged
Agent has preferable visible light catalytic efficiency, can effective photocatalytic degradation antibiotic waste water, especially concentrated hydrochloric acid four
Ring element and sulfamethazine antibiotic waste water.In addition, the photocatalyst material prepared by the present invention is for water middle and high concentration
Dyestuff contaminant also have good degradation effect.

3) stirring under confined conditions by solution at 200~230 DEG C keeps the temperature 6~8h；
4) centrifugation obtain black precipitate, after clean with deionized water and ethyl alcohol, 60~80 DEG C be dried in vacuo 18~for 24 hours after,
Grinding obtains required photochemical catalyst powder；
The photocatalytic degradation application of 2 antibiotic waste waters
1) use 300W xenon lamps as photocatalytic degradation light source.
2) the mesoporous molybdenum disulfide visible light catalysts of 0.1g are scattered in 100~150ml high concentration antibiotic solutions, often
3~5ml solution is taken every 5~15min；
3) taken solution after centrifugation is taken into supernatant liquor and tests its extinction number of degrees with uv-visible absorption spectra instrument
Value.
Compared with prior art, the beneficial effects of the invention are as follows：Molybdenum disulfide visible light catalyst material prepared by the present invention
