Description
Technical field
The present invention relates to inorganic functional material preparation technical fields, and it is useless to be related specifically to a kind of processing methylene blue dye
Catalyst of water and its preparation method and application.
Background technique
Organic dye waste water has become one of main pollution source of water body at present.The waste water have water is big, concentration is high,
The features such as complicated component, coloration are deep and difficult to degrade.Most of dyestuffs also have toxicity, carcinogenicity, teratogenesis and mutagenic effect.
Methylene blue is a kind of important organic chemical synthesis dye of positive ion, and industrial application is very extensive.For example, can be applied to fiber crops,
Silk fabric, the dyeing of paper and the coloring of bamboo and wood, applied to biology, the dyeing of bacterial organisms and applied to manufacture ink
With color lake etc..The extensive use of methylene blue industrially also leads to the serious dirt containing methylene blue dye wastewater to water body
Dye.The processing method of organic dye waste water mainly has bioanalysis, Coagulation Method, high-level oxidation technology, photocatalytic method, absorption method at present
And membrane separation process etc..Bioanalysis is influenced by factors such as pH value, temperature, salt and dyes, so that the effect of Biochemical method
Fruit is not ideal enough.The operating cost of Coagulation Method is higher, and body refuse amount is big and dehydration is difficult, and applicable pH value range is narrow.Advanced oxygen
It is high to change technical costs, common oxidant can also show the disadvantages of oxidability is not strong, there are selective oxidations, and processed
It is readily incorporated impurity in journey and causes secondary pollution.Photocatalytic method needs light source to irradiate system, is influenced in practical applications by weather
Greatly.Absorption method vulnerable in water suspended matter and grease etc. influence, and adsorbent amount is greatly and costly.Membrane separation process is divided into electricity
Dialysis, hyperfiltration, nano filtering process and ultrafiltration etc., wherein the advantages of electroosmose process, hyperfiltration, nano filtering process is dyestuff removal
Rate is high, can recycle the dyestuff in waste water, simple process, but the higher cost of film used, and operating pressure is larger, causes embrane method
Energy consumption is higher, affects its industrial applications.Traditional ultrafiltration is larger due to membrane aperture, it is difficult to remove the organic of low molecular weight
Pollutant.Therefore, it develops one kind simply and the catalyst of efficient process methylene blue dye wastewater has great importance.
Prior art discloses one, application No. is 201210145478.4 patent application " double-layer catalyst and its preparations
And the catalyst is preparing the application in equal acid anhydride " contain effective quantity active constituent V2O5、TiO2、P2O5、Na2O、MoO3、Sb2O3、
The compound and whisker of other metals weighed respectively, with liquid, with spraying slurries, the techniques such as be sprayed on carrier, roast, cool down
Catalyst E, G is made in step, and catalyst G, E are respectively placed in material mixed gas arrival end and reaction gas outlet end, low-speed,
Equal acid anhydride is prepared under the conditions of lower temperature etc., but the catalytic component is various, preparation process is complicated, and catalyst obtained need to be
Temperature uses under the conditions of being 400~430 DEG C, and energy consumption is high.
Present inventor discloses several prior arts relevant to present patent application before this, for example, application
Number for 201310014950.5 patent application " it is a kind of handle methylene blue dye wastewater carbon monoxide-olefin polymeric preparation side
Method " and that application No. is 201210474494.8 patents is " a kind of for handling the catalyst combination of methylene blue dye wastewater
Object and its preparation method and application ", it is K that general formula, which is respectively adopted, in this two applications2O•Cr2O3•xMoO3(x=1~8) and Na2O•
Cr2O3•xMoO3The ternary compound oxides of (x=1~8) are as catalyst degradation methylene blue dye wastewater, but the two is degraded
Time is longer, need 60 minutes or more, in addition rare metal content contained by catalyst is high, at high cost.Therefore, still need to be developed
A kind of NEW TYPE OF COMPOSITE oxide reduces rare metal content in catalyst while guaranteeing above-mentioned dyestuff degradation rate.
Summary of the invention
In view of the deficiencies in the prior art, it is an object of the invention to solve the above-mentioned technical problems in the prior art,
To provide a kind of catalyst and its preparation method and application of simple and effective degradation of methylene blue waste water.
To achieve the goals above, the technical solution of the present invention is as follows:
A kind of catalyst handling methylene blue dye wastewater, the general formula of the catalyst are CuNiSbSnSi4O13.5。
A kind of preparation method for the catalyst handling methylene blue dye wastewater, the method carry out as follows:
1, it prepares gel: copper nitrate, nickel nitrate, antimony trichloride and tin tetrachloride being completely dissolved in water at normal temperature, stirred
Lower dropwise addition tetraethyl orthosilicate is mixed, after being added dropwise, continues stirring until generating gel；
2, prepare catalyst powder: the gel drying that step (1) is obtained and grind into powder, obtaining general formula after calcining is
CuNiSbSnSi4O13.5Catalyst powder.
Copper in the catalyst powder, nickel element, antimony element, tin element and element silicon molar ratio be 1:1:1:
1:4.
The gel that preparation generates is dried into simultaneously grind into powder at a temperature of 100 DEG C 140 DEG C.
