Description
Technical field
The present invention relates to application of the adsorbent in adsorpting anion dyestuff, and in particular to a kind of based on magadiite
Environmental-protection adsorption material and preparation method thereof and the application in anionic dye adsorbs.
Background technique
With the raising of China's industrialization degree, water pollution problems is increasingly prominent, and especially industrial wastewater is unprocessed just
Be discharged into water body environment, the sustainable development of the serious health for influencing the mankind and society, and organic dye waste water be it is a kind of very
Intractable industrial wastewater, the feature of high, causing toxicity, carcinogenicity, non-biodegradable and biodegradability difference with concentration, i.e.,
Make lower concentration that also can the mankind and microorganism be caused with very big harm.Therefore it needs to handle it before discharge.
Numerous scholars further investigate wastewater treatment project both at home and abroad, are dedicated to inventing various new technologies, the various green woods of exploitation
Expect, explore various new processes, alleviates the contradiction of supply and demand for the water resource.All multi-methods are used for sewage treatment, including coagulation, flocculation, heavy
Shallow lake method, Ozone, oxidizing process, photocatalytic method and microwave radiation.These methods are there are at high cost, pollution environment or are difficult to all go
The defects of depollution object.Absorption method is one of most efficient method in sewage disposal technology, and water can be effectively removed in adsorbent
Middle various pollutants, especially other methods are difficult to the toxic and difficult to degrade pollutant being effectively treated；Meanwhile adsorbent reactivation
Technical research deepens continuously, and has more widened the development space and application prospect of absorption method in the treatment of waste water.The layer of low cost
Shape silicate-base adsorbent material has adsorption effect, interlayer cation exchange interaction, duct filtration and special nanometer
The special natures such as structure effect have become home and abroad environment contamination control and repair one of the research hotspot in field, main to use
The removal of volatile organic contaminant and as soil in heavy metal in waste water, organic pollutant, dyestuff, red tide and atmospheric environment
Earth pollution amelioration material etc..Common phyllosilicate is montmorillonite, but montmorillonite purity is low, and ion exchange capacity is not high, opens
It adopts and brings environmental pollution, and sheet surfaces, substantially without structural hydroxyls, functional modification is restricted, it is difficult to be widely applied.
Therefore new phyllosilicate adsorption production is researched and developed, reduces the exploitation of natural mineral resources, reduces the processing cost of waste water
It has a very important significance.Compared with montmorillonite, magadiite (magadiite) is had the advantage that first is that controlling conjunction
At technique, the product of high-purity can be obtained；Second is that laminate has excellent expanded performance, interlayer cation exchange capacity is much larger than
Montmorillonite can guarantee excellent absorption property；Third is that the single lamella of magadiite is thicker (1.12nm), structural stability is good；
Fourth is that containing more hydroxyl groups on lamella, functional modification can be carried out, fifth is that can be artificial synthesized, it avoids opening in nature
It adopts and bring environmental disruption；Sixth is that it is cheap, there is market competition advantage.Magadiite can substitute nature completely
Montmorillonite, realize protection and sustainable use to mineral resources, reduce valuable mineral resources be used inefficiently and
Caused waste.Also effectively uncontrolled unauthorized and wasteful mining of the containment to mine simultaneously, protects forest vegetation, maintaining ecological balance.Though
Right magadiite absorption property is more than montmorillonite, but its absorption property or to be improved.
Summary of the invention
The purpose of the present invention mainly overcomes deficiency in the prior art, provides QCS-magadiite nano-hybrid material
Application in adsorpting anion dyestuff.
To achieve the above object, the technical solution adopted by the present invention is as follows.

(3) the organically-modified magadiite is dispersed in water, after ultrasound, mechanical stirring, obtains organically-modified wheat hydroxyl
Silicon sodium stone uniform dispersion；
(4) n-trimethyl chitosan chloride is added in the organically-modified magadiite dispersion liquid in the step (3), and machinery stirs
It mixes to fully reacting；
(5) reaction product filtering in step (4) is taken out, the post-treated obtained environmental protection based on magadiite is inhaled
Enclosure material.
Preferably, the additional amount of cetyl trimethylammonium bromide and the mass ratio of magadiite in the step (1)
It is 30%-50%, with the mass ratio of organically-modified magadiite is 11%-15% in step (4) n-trimethyl chitosan chloride.
Preferably, the anionic dye initial concentration range is 50~130mg/L.
Preferably, reaction condition is 60-80 DEG C of magnetic agitation 6-8h in the step (2), and uses deionized water after filtering
Washing 2-3 times, at 60-80 DEG C more than drying for 24 hours.
Preferably, post-processing described in step (5) is washed with deionized 2-3 times after filtering, the 60- in vacuum drying oven
80 DEG C of freeze-day with constant temperature for 24 hours more than, finally grind.
Application of the above-mentioned environmental-protection adsorption material being prepared in anionic dye absorption.
Preferably, anionic dye initial concentration is 50~130mg/L in staying water.
Preferably, after anionic dye being added in QCS-magadiite nano-hybrid material, adsorption time 40-60 minutes.
Preferably, after anionic dye being added in QCS-magadiite nano-hybrid material, adjusting water pH value is 4-9.
Preferably, the anionic dye be xylenol orange, methyl orange or it is Congo red in it is any one or more.
Preferably, the adsorption reaction is to carry out at normal temperature.
The ion-exchange performance that this method has according to magadiite interlayer, with n-trimethyl chitosan chloride cationic polymer
(QCS) ion exchange is carried out, i.e. cationic polymer QCS enters the piece interlayer of magadiite by ion exchange, carries out
LBL self-assembly reaction prepares intercal type QCS-magadiite nano-hybrid material, using this material as novel water treatment agent,
Purified treatment for sewage.
Compared with prior art, the invention has the advantages that and technical effect: have with QCS and CTAB to magadiite
