Description
Technical field
The invention belongs to waste textile processing technology field, and in particular to one kind is using polymer fiber material as matrix amine
Change the modified method for preparing sorbing material.
Background technology
The waste textile total amount that China produces every year has more than 2,400 ten thousand tons, wherein be able to recycle less than ten thousand/
Three.In textile fabric, the yield sum of terylene and cotton fiber accounts for more than the 70% of all textile fabric yield.Traditional is waste and old
Textile processing approach has burning and buried, and air, soil, water environment are polluted.Waste textile is carried out to reclaim profit
Method includes mechanically decoupled, chemical degradation etc..The main component of bafta is cellulose, and content of cellulose accounts for 90%-
94%, it is phosphorus content highest natural polymer, its chemical constitution is with β-Isosorbide-5-Nitrae glucosides by β-D- glucopyranosyls
The linear polymeric of key connection, in addition also hemicellulose, soluble saccharide, pectin, wax, fat, nitrogen substance, ash content
Deng.Terylene is also referred to as polyester, belongs to high-molecular compound.It is to be produced by terephthalic acid (TPA) (TPA) and ethylene glycol (EG) by polycondensation
Raw polyethylene terephthalate (PET), is a class excellent performance, widely used engineering plastics, terylene molecule is by short fat
Fat hydrocarbon chain, ester group, phenyl ring, end alcoholic extract hydroxyl group are constituted.Collagenous fibres are the straight chain knots of a kind of appearance white, transparent natural fiber
Structure protein, is largely present in the skin histology of mammal, knot hoof tissue and bone tissue, belongs to natural polymer
Material.Contain a large amount of carboxyls, amino, hydroxyl isoreactivity group in collagenous fibres molecule, with very high chemism.
Copper, as heavy metal, is one of animals and plants and the essential trace element of human body, excessive copper has to organism
Very big harm, because it can be combined with the sulfydryl in protein, disturbs the normal activity of sulfydryl enzyme, when copper is in people's cylinder accumulation
To after certain amount, animals and plants will be made damage symptoms occur, physiology is obstructed, arrest of development, in addition it is dead；Soil can also be made
Poisoning, influences the physicochemical property of soil, constituent, pH value etc..Most of dyestuffs are all the organic matters of poisonous difficult degradation, chemistry
Property is stable, with carcinogenic, mutagenesis, teratogenesis, the health of the mankind can be directly endangered, to soil, water body and ecological ring
Cause very serious breaking-up in border.Excessive phosphorus can cause the eutrophication of water body, stimulate algae and bacterium amount reproduction, cause water
Matter deteriorates.When the concentration of the marine phosphorus in lake is more than 0.03mg/L, it will occur red tide, cause water quality to be degenerated.For these water bodys
In common pollutant, absorption method is a kind of simple, the easy to operate treatment technology of technique.At present, occur in that a large amount of using useless
The gurry such as cheap raw material such as flyash, rice husk, stalk, leaf as sorbing material report, but on waste textile fiber
Sorbing material with collagenous fibres is also rare.The present invention is based on the abundant active group in bafta, terylene, collagenous fibres surface
Group, amination modification is carried out using dopamine, and addition oxidant carries out catalysis oxidation, synthesizing new environmentally conscious materialses, reaction condition temperature
Simple with, operating procedure, modifying process is easily controlled.
The B of CN 103409940 are disclosed《For the preparation side for the dopamine composite nano fiber affinity membrane for adsorbing La3+
Method》, La is adsorbed using being used for obtained by this method3+Dopamine composite nano fiber affinity membrane, including：

Metal ion La3+Dopamine composite nano fiber affinity membrane；Wherein soaking temperature is 20~40 DEG C, pH=6.0-10.0, leaching
The bubble time is 2~48h.
Adopt fiber affinity membrane resulting with the aforedescribed process, can be widely applied to absorption absorption and separate and chemistry spy
Pin, sensor, the field such as water process.
Obtained fiber affinity membrane, is limited only to the Adsorption of metal ion, for waste water water in method above
The removal of dyestuff and anionic pollutant phosphate anion in body, does not obtain corresponding significant effect.
Accordingly, it would be desirable to invent a kind of not just in metal ion and waste water dyes can be widely used in
With the Adsorption material of anionic pollutant phosphate radical etc..
The content of the invention
In order to solve above-mentioned technical problem, changed the invention provides one kind based on waste textile fiber and collagenous fibres
Property prepare environmentally conscious materialses method, by the present invention method to waste textile fiber treatment, be utilization of waste as resource
There is provided valuable developing direction.
The method that the amination modifying using macromolecular fibre as matrix of the present invention prepares sorbing material, it is mainly fine in such as cotton
Buffer solution and oxidizer treatment containing dopamine are added in dimension or polyester fiber material, sorbing material is obtained；Either by high score
Subbundle material adds oxidizer treatment, obtains sorbing material by pretreatment.
Idea of the invention is that, it is discarded macromolecular fibre using reaction raw materials cheap and easy to get, such as cotton fiber, washs
Synthetic fibre fiber or collagenous fibres etc., fiber-based material is after the imitation biochemistry modification and the oxidation of oxidant of dopamine, in fiber base
Oxidation polymerization occurs for material surface, forms a strata dopamine film.Thus, the substantial amounts of phenol hydroxyl of fiber-based material surface grafting
Base, amino, quinonyl, can combine with copper ion, the pollutant such as dye molecule and phosphate radical, obtain a kind of multi-functional environment material
Material, the material is easily isolated and recycled, and the removal rate to polluter is fast, applied widely.
The method that amination modifying sorbing material is prepared by matrix of polymer fiber material, adds in polymer fiber material
Enter the cushioning liquid containing dopamine, add oxidizer treatment, obtain sorbing material.
