Description
Technical field
The present invention relates to a kind of method removing waste water from dyestuff Methylene Blue, specifically by α-MoO3Particle room
The lower efficient absorption of temperature removes the methylene blue in waste water from dyestuff, belongs to the preparation and application field of adsorbent.
Background technology
Methylene blue, also known as methylene blue, methylene blue, alkalescence acid blue, is the heteroaromatic compound of a kind of phenothiazine salt.
Methylene blue is the cationic organic dyestuff of industrial normal use, is widely used in weaving, leather, papermaking, dyestuff, plastics etc.
Field.At present, the field such as industrial papermaking, chemical industry, dyeing and weaving produces a large amount of waste water dyestuffs, causes environmental pollution, water plant light
Close ability to function decline, mankind's Nausea and vomiting, cancerous lesion.Therefore, along with the continuous enhancing of environmental consciousness, sub-containing Organic substance
The dye wastewater treatment of methyl blue is of great interest.
In dyeing waste water, dye molecule contains substantial amounts of polar group, and main minimizing technology has: membrance separation, photocatalytic degradation
And absorption.Membrane separation process refers to that waste water, by having selective semipermeable membrane, using gradient difference as the power separated, utilizes organic
Thing molecule and the particle diameter difference of hydrone, it is achieved dye molecule separates with water.The method has that energy consumption is low, selectivity good, dirty
Contaminate the advantages such as little, but operating cost is high, easily occur the shortcomings such as blocking to constrain its application.Photocatalytic oxidation is to utilize quasiconductor
Material is catalyst, under light illumination the organic matter degradation in waste water from dyestuff is converted into CO2、H2O, inorganic salt etc. to environment without
The material of evil.This technology low energy consumption, non-secondary pollution, be a kind of cleaning, efficient governing measure, but use in photocatalytic process
The uviol lamp life-span short, costly, limit its industrial applications.Absorption method is by adsorbent big for surface energy and waste water dyestuff
Contact, utilizes the approach such as Van der Waals force, chemical bond, by the Adsorption of Organic in waste water to surface, it is achieved water quality is clean
Change.From the point of view of environmental friendliness and reaction efficiency, for processing the dyestuff being difficult to degrade, toxicity is the biggest in waste water, inhale
Attached method has preferable advantage, owing to adsorbent is water insoluble, it is easy to collect, and reaches to separate and the purpose of enrichment pollutant.Cause
This, utilize adsorption technology to remove waste water dyestuff, owing to its low cost, efficiency are high, simple to operate, have in water treatment field wide
Application prospect.
At present, active adsorption waste water from dyestuff is concentrated mainly on activated carbon and material with carbon element system.Such as: Zhang etc. report
Graphene oxides nanometer sheet at room temperature absorption property to methylene blue, finds when methylene blue concentration is 15mg/L
The highest, removal efficiency is 95% (Z.J.Zhang, et al., RSC Adv., 2015,5,27,922 27932).Zhou etc. report
Mesoporous carbon micron ball is at H2O2、NH2Under OH system, when adsorption concentration is the methylene blue solution of 40mg/L, 30 DEG C of contacts
The removable methylene blue of 40min.(L.C.Zhou,et al.,Appl.Mater.Interfaces,2014,6,7275-7285).
The report activated carbon such as Huang at room temperature can methylene blue in efficient absorption waste water, maximum equilibrium adsorption capacity is
581.4mg/L (H.Huang, et al., Ind.Eng.Chem.Res., 2013,52,14297-14303).
Although these carbon-bearing adsorbents can be with the methylene blue dye in efficient removal waste water reusable edible, but carbon material
Expecting expensive, processing cost is higher, regeneration difficulty, is not suitable for the process of high density pollution thing, limits its commercial Application.Mesh
Before, the research to adsorbent is concentrated mainly on efficient, the multi-functional and adsorbent of low cost of searching.Metal-oxide is as a class
Novel absorption material attracts attention, and goes a good appetite suddenly appearing in a serious disease to show the performance of excellence at the dyestuff such as methyl orange, methylene blue
(J.R.Chen,et al.,Appl.Surf.Sci.,2016,378,80–86；A.L.Meng,et al.,ACS
Appl.Mater.Interfaces 2015,7,27449-27457).But about effective for waste water dyestuff of molybdenum oxide material
There is not been reported for Adsorption, therefore, and research molybdenum oxide material controlledly synthesis and regulation and control so that it is can highly active absorption waste water
In methylene blue, there is certain practical value.
Summary of the invention:
It is desirable to provide one is with α-MoO3Particle is the method that adsorbent removes waste water from dyestuff Methylene Blue, can
α-the MoO of control synthesis3Particle can remove the methylene blue in waste water with efficient absorption, it is achieved the clearance of 100%.

m。
2) by α-MoO3Particle is for the adsorption treatment of waste water from dyestuff Methylene Blue.α-MoO3Particle at room temperature adsorbs
Methylene blue concentration is the waste water of 1-800mg/L, and adsorption time is 0.5-12h, and methylene blue adsorption number clearance is 100%.
3) by α-MoO3Particle, for the waste water from dyestuff adsorption treatment of 100mg/L methylene blue, after absorption terminates, is isolated
Adsorbent, places it in Muffle furnace, is raised to 500 DEG C from room temperature in air atmosphere, and keeps 2h in this temperature, removes absorption
Organic substance, adsorbent α-MoO3Particle restores, and has carried out 4 circulation experiments altogether, and 4 times adsorption experiment methylene blue in waste is gone
Except rate is 100%.
Relative to current existing adsorbent, present invention have the advantage that
1) by controlledly synthesis α-MoO3Particle, it is achieved that effective removing of waste water solution Methylene Blue, Adsorption
Rate is 100%.
