Description
One, technical field
The present invention relates to a kind of new purposes of known substance, the new purposes of particularly a kind of native protein metallic substance in environmental protection exactly is the purposes of eider down in the water-insoluble organic solvent prevention and cure of pollution.
Two, background technology
Chemical industry is after Coal Chemical Industry develops into petrochemical complex, the kind of organic solvent, quantity and the application on industry thereof are increasingly extensive, to society, expanding economy plays positive pushing effect, but the steady hidden danger of the safety of organic solvent in production, storing, use, the poisonous and harmful solvent environment accident of particularly meeting burst by chance but can not be ignored.For example, on November 25th, 2005, the preserved egg river pollution incident because of the explosion hazard burst of the two benzene factories of Jiization has startled the whole nation, has also startled the world, because Song Hua River and river, downstream thereof are referred to as mother river.The floating waters surface such as the benzene lighter than water, toluene go downstream, and also will bring disaster to Heilungkiang, with river etc., though diluted remaining in the water body; The oil of mirbane heavier than water, aniline etc. are deposited in the bottom, are adsorbed in the silt, are trapped on the riverbed.Adopt activated carbon to administer and have open defect, this is not still had at present administer and remove good plan.
According to the statistics of State Environmental Protection Administration to 41 industrial trades in the whole nation, the paper-making industry wastewater emission amount was 31.8 hundred million tons in 2004, occupied the second, chemical industry production rank first (" Science and Technology Daily " on December 9th, 2005 the 7th edition).As seen national wastewater emission amount is very surprising, wherein is no lack of the waste water that contains organic solvent, particularly contains the waste water of water-insoluble organic solvent.Present improvement to this type of waste water, perhaps physical adsorption, perhaps dilution discharge is perhaps buried transfer.
The adsorbed oil material (sorbent material) of physical adsorption mainly contains gac, crop straw, sawdust, nonmetalliferous ore soil and the oil absorbent material of being processed by natural fiber or synthon, oil suction cloth etc., 10～20 times of oil suction multiplying powers, and speed of oil absorption was less than 5 minutes.
It is monomer that CN1442438A discloses with the esters of acrylic acid, by the high oil absorbing resin that free radical suspensioning polymerization prepares, and the oil suction multiplying power: gasoline, diesel oil＞10g/g, aromatic hydrocarbons＞20g/g, halogenated aryl hydrocarbon class＞30g/g, maximum oil suction multiplying power is 37g/g.
CN1417263A is open to be the degradable oil absorption material of raw material reaction preparation with sugarcane bagasse and aceticanhydride.The open biodegradable oil absorption material that is the main raw material preparation with the poly-beta-hydroxy-butanoic acid valerate of biological fermentation process of CN1313348A.
Water resources is the important assurance that China realizes the strategy of sustainable development.Yet China's water resources per capita only is 1/4 of the world, and the continuous pollution at water body, water source makes this very short water resources nervous more, and the whole nation has 600,000,000 populations to drink contaminated water, still has the tens of millions of people to can not get enough tap water every day in addition.Therefore protecting limited water resource is very urgent, as a to be imminent major issue.
Eider down, feather belong to natural protein class material, and shape is assorted shape, sheet.Eider down, feather be hydrophobic extremely, and the relation of identical lotus leaf and water is not soaked into, do not adsorbed, and a little attaches, and one trembles promptly.Eider down, feather be soft, sliding, loose, loose, and one touches promptly and flies, and does not have cohesive force each other, does not possess spinning property.People utilize its slim and graceful, soft, fluffy advantage for a long time, as natural heat insulating material formed clothes, the quilt pillow of being applied to, as down jackets, eiderdown quilt etc.Only there are the Japan and the U.S. that eider down, feather are pulverized in recent years, are applied to other field with other powder material mixing post-treatment light heat insulation materials.
Three, summary of the invention
The applicant removes in the experiment at an organic solvent, adopts down fiber directly to absorb benzene, and down fiber exhausts rapidly and moment forms a gel.It is dropped in the water, can swim on the water surface, brute force stirs also not disintegration down, indiffusion, but can separate by centrifugal or squeezing, crowded strand, makes eider down regeneration.Further experiment shows, except that benzene, water-insoluble organic solvents such as toluene, chlorobenzene, oil of mirbane, aniline and fat alkane, alicyclic ring alkane touch behind the eider down also that moment forms gel, also bubble through the water column, not disintegration under powerful stirring the, indiffusion, but separable regeneration eider down.
Proportion forms the phenomenon of gel when touching eider down greater than the water-insoluble organic solvent of water magical more: organic solvent can be trailed the eider down that upwards floats, and pursues to the water surface always and forms gel.Experiment is done like this, adds tap water in the 100ml beaker, adds 2～3ml oil of mirbane (proportion 1.198, SI chemical data table) again, and lurid oil of mirbane sinks rapidly, at the bottom of accumulating in glass.At the bottom of clamping a handful of eider downs and send into glass with tweezers, unclamp tweezers when eider down rigidly connects rapidly when contacting oil of mirbane, at this moment eider down is just upwards floating, and oil of mirbane is just as " the wind post " that risen by wind spout, and trailing eider down rises together, forms gel up to the water surface.Oil of mirbane is all inhaled to coagulate.
The applicant mixes the back input with 100ml oil of mirbane and fills in the 500ml beaker of water with 50g earth, mud sinks under water rapidly, after half an hour, there is a small amount of oil of mirbane desorption to float on the mud layer surface, at this moment clamp the pugil eider down with tweezers and stir in mud, unclamp tweezers, a gel emerges, not disintegration, indiffusion.
The application people claims that water-insoluble organic solvent is to inhale coagulation phenomena by the phenomenon of eider down absorption and gelation rapidly, and this new performance that claims eider down is for inhaling characteristic with fixed attention.After measured, eider down can be inhaled the various organic solvents that coagulate 35～40 times of own wts, gelation process only 2～10 seconds, and visible eider down has quick suction to coagulate effect to water-insoluble organic solvent.The performance that this of eider down is new should have new purposes, and Here it is, and eider down can be used as the application for preparing in the purification separation material of preventing and treating water-insoluble solvent pollution usefulness.
China produces 600000 tons on eider down, feather per year, and annual total output and export volume account for more than 70% of general trade amount of world's eider down, feather ultimate production.Because present main application is that warming usefulness core material, processing are extensive, there is considerable part to go out of use, also has a great deal of depleted core material in addition, the depleted eider down can cause organic contamination, because eider down, feather not perishable, the degraded of the utmost point under field conditions (factors), one aspect of the present invention has found new purposes for the depleted eider down, and the improvement of also polluting for organic solvent provides new scavenging material on the other hand.
One ton of eider down can be inhaled the water-insoluble organic solvent that coagulates 35～40 tons.Eider down is processed into suitable purification separation material, can carry out purifying treatment to water body, water source and the mud that has been polluted on the one hand by organic solvent, can be used as the strategic reserves goods and materials on the other hand, prevent trouble before it happens, the end treatment that contingent and occurent organic solvent is polluted becomes the source prevention and control.The organic solvent of inhaling after coagulating can reclaim use, and the eider down sorbing material uses repeatedly, last burning disposal.
