Background technology
Polyaniline (PANI) has unique physicochemical property and certain absorption property, is the novel substance that a class being is is being researched and developed.The people such as Mahanta adopt chemical method to prepare polyaniline under strongly acidic conditions, and it shows better absorption property for containing sulfonic anionic dye, for then not showing good absorption property containing sulfonic dyestuff.The people such as Ai under strongly acidic conditions, adopt chemical method to prepare the polyaniline microsphere that average grain diameter is 2.2 μm, and are applied to the Adsorption of methyl orange in water.But because polyaniline particles particle diameter is less, easily reunite, adsorbed rear separation difficulty or fixed bed resistance comparatively large, be not suitable for continuous adsorption or the Dynamic Adsorption process of industrial wastewater.
Research finds, PANI and large biological molecule interphase interaction, can give PANI-bimolecular complexes better performance.The large biological molecule that report attempts using has the extracellular polymeric, starch etc. of shitosan, bacterium.As Janaki etc. in acid condition, polyaniline/the Chitosan Composites that utilized chemical oxidization method to prepare, with pure polyaniline compound seemingly, have selective to the absorption of dyestuff in water, better to the adsorption effect containing sulfonic anionic dyes, but to cationic dyes less effective.Starch/the polyaniline nano-composite material that utilized chemical oxidization method to prepare such as Janaki, for containing sulfonic dyestuff, there is good absorption property in acid condition, when optimal adsorption effect appears at pH=3, its practical application that is restricted to of service condition is made troubles.
The preparation method of current polyaniline mainly contains chemical method, electrochemical process and biological enzyme three class.Wherein, biological enzyme is a kind of method of comparatively environmental protection, but biology enzyme is owing to limiting by factors such as environment, source and prices, fails extensively to be applied.Imitative enzyme process, by building the system similar to biology enzyme, carries out the synthesis of polyaniline under mild conditions, turn avoid enzyme easy in inactivation, to shortcomings such as requirement for environmental conditions are higher simultaneously.Hemin (Hemin) is the Small molecular with ferriporphyrin structure, and have the character similar to peroxidase, early-stage Study shows, it can be used to the polymerization carrying out aniline.
Cellulose is the abundantest on the earth, reproducible natural polymer biological material.China is as a large agricultural country, the annual production of crop material is huge (can reach about 700,000,000 tons), and current straw utilization rate is very low, wherein major part also just directly utilizes as fuel etc., brings the problems comprising atmospheric haze thus.In plant material, content of cellulose is the highest, can account for 40 ~ 50%, so based on cellulose exploitation new material, the prospect realizing the higher value application of living beings is boundless.Carboxyl methyl cellulose is nonpoisonous and tasteless, wide material sources, be at present most important, output is maximum, use cellulosic products the most easily.
Summary of the invention
The invention provides a kind of eco-friendly imitative enzymatic and prepare PANI-CMC compound, and as adsorbent, be applied to the process of waste water from dyestuff.
A PANI-CMC compound adsorbent prepared by imitative enzymatic, prepared by following steps:
In buffer system, add the aniline of certain mass ratio, X-factor (Hemin) and CMC, make it be uniformly dispersed; At room temperature, constantly stir, in system, add a certain amount of H every 15-20min
2o
2; Continue reaction more than 0.5h, in system, add a certain amount of hydrochloric acid, make reaction continue to react more than 30min in sealing situation, leave standstill by water and ethanol washed product after a period of time, and by product drying at not higher than 60 DEG C, after grinding, obtain powdery product.
In above-mentioned reaction, buffer system is selected from the one in acetic acid-sodium acetate, citric acid-sodium citrate, and pH value range is 3 ~ 6; The mass ratio of aniline, Hemin and CMC is 1:0.01:0.2 ~ 0.8; Aniline, hydrochloric acid and H
2o
2mol ratio be 1:6 ~ 30:0.15 ~ 1.5; Time of repose is 10 ~ 20h.
The application of above-mentioned compound adsorbent PANI-CMC in dye wastewater treatment.
Compared with prior art, tool of the present invention has the following advantages:
1, catalystic converter system environmental protection, reaction condition is gentle.
2, compared with polyaniline, the product P ANI-CMC obtained not only has good absorption property for containing sulfonic anionic dye, also has good absorption property for the dye of positive ion.
3, product P ANI-CMC (pH=3 ~ 11) under wider pH condition has better adsorption effect simultaneously, and range of application is expanded.
