Description

A kind of preparation of hydroxyethyl cellulose/concave convex rod/sodium humate composite aquogel and Using
Technical field
The present invention relates to a kind of organic/inorganic composite aquogel, more particularly to a kind of hydroxyethyl cellulose/concave convex rod/corruption The preparation method of sour sodium composite aquogel is grown, the present invention also relates to suction of the gel as adsorbent to methylene blue dye Echo use, belongs to sorbing material field and dye wastewater treatment technology field.
Background technology
With modern textiles, printing and dyeing industrial expansion, substantial amounts of methylene blue dye wastewater is emitted, no Environmental pollution is only caused, but also has harm to health.Therefore, methylene blue is removed from waste water from dyestuff to seem particularly It is important.The method of generally removal methylene blue has absorption method, biological degradation method and electrochemical process etc., and wherein absorption method has operation Simply, power consumption is widely adopted less, the advantages of effect is good.Therefore, cheap and effective adsorbent is produced by the wide of people General research.
Cellulose is natural polymer most ancient on the earth, most abundant, is inexhaustible, and the mankind are most precious Expensive natural reproducible resource.Hydroxyethyl cellulose（HEC）It is a kind of white or faint yellow, tasteless, nontoxic fibrous or powder Last shape solid, by alkali cellulose and oxirane（Or chlorethanol）Prepared by etherified reaction, category nonionic soluble fibre element Ethers.Because HEC has good thickening, suspension, dispersion, emulsification, bonding, film forming, protection moisture and provides protecting colloid etc. Characteristic, has been widely used in oil exploitation, coating, building, medicine food, weaving, papermaking and macromolecular polymerization reaction etc. Field.
Attapulgite is allowed to many special materializations and processing performance due to unique crystal structure.Main materialization Performance and processing performance have：Cation interchangeability, water imbibition, adsorption bleaching, big specific surface area and colloid index and swollen Swollen appearance, therefore can be used for agriculture water conservation moisturizing and the treatment of dye wastewater.
Sodium humate is that have various work(through one kind that special process is processed into by raw material of weathered coal, peat and lignite The macromolecular organic monoacid sodium salt of energy, its structure is more complicated, it is known that contain phenyl ring, condensed ring and some heterocycles in humic acid molecule （Such as pyrroles, furans, indoles）, there is bridged bond to be connected between each aromatic rings, there are various functions group, mainly carboxylic on aromatic rings Base, phenolic group, hydroxyl, methoxyl group, quinonyl etc..Humic acid contents on dry basis is more than 75% in sodium humate, due to humic acid molecule in itself Amount is larger, and bigger particle can be also associated with certain medium, therefore with colloid property and adsorption capacity, is formed good Ion exchange and catalytic action.
However, having not yet to see about hydroxyethyl cellulose, concave convex rod, the research of sodium humate composite and report.
The content of the invention
The purpose of the present invention is the property using the mode of hydroxyethyl cellulose, concave convex rod and sodium humate, and three is led to Cross certain mode to be polymerized, obtain a kind of composite --- ethoxy with good swelling behavior and absorption property The preparation method of cellulose/concave convex rod/sodium humate composite aquogel；
It is a further object of the present invention to provide above-mentioned hydroxyethyl cellulose/concave convex rod/sodium humate composite aquogel in methylene Application in blue dye wastewater treatment.
First, the preparation of HEC-g-APT/SH composite aquogels
Hydroxyethyl cellulose is scattered in distilled water, 60 ~ 70 DEG C are heated to, 10 ~ 15 min of stirring make solution into thick；Plus Enter initiator solution and stir 10 ~ 20 min to produce free radical, add the acrylic acid of degree of neutralization 55 ~ 75%, concave convex rod and humic The mixed liquor of sour sodium, 30 ~ 50 min of stirring are well mixed its reactant, and temperature then is raised into 10 ~ 20 DEG C, react 2 ~ 4 h, Composite aquogel product is obtained, finally composite aquogel product is cut into small pieces, soaked 10 ~ 15 h with ethanol and do not reacted with removing Complete monomer and autohemagglutination product, dries to constant weight, obtains final product hydroxyethyl cellulose/concave convex rod/sodium humate product HEC-g-APT/ SH。
