Description
Technical field
The present invention relates to a kind of preparation of oil absorbent packet, this device is the nonwoven oil absorbent packet that is packaged with novel absorption material ZIF-8, this absorbent packet adopts the mode of heat bonding to encapsulate, and develops a kind of method of novel fast simple removal sea oil pollution with this.
Background technology
ZIF-8 is the rigid backbone porous adsorbing material with special cage structure that a class is formed by self assembly effect by metal ion and organic ligand.The well-regulated pore passage structure of ZIF-8 tool, (BET specific area is up to 2000m for the specific area of super large
2/ g), the remarkable advantages such as good heat endurance and solvent stability, therefore, have been widely used in the absorption of organic pollution.The present invention adopts this novel porous adsorbing material of ZIF-8 as adsorbent, prepares nonwoven oil absorbent packet, and for the quick removal of sea oil pollution.
Nonwoven, refers to non-weaving cloth, or is adhesive-bonded fabric.Be a kind of fabric that does not need to spin cotton and weave cloth and form, this fabric just carries out orientation or random support row by textile staple or long filament, forms fibre net structure, then adopts the method reinforcing such as mechanical, hot sticky or chemical to form.Non-weaving cloth has been broken through traditional weaving principle, have that technological process is short, speed of production is fast, the features such as output is high, cost is low, purposes is wide, raw material sources are many, therefore, in recent years, nonwoven textile industry has obtained great development, ends 1998, and global nonwoven consumption figure has reached 2,400,000 tons.
Oil has become one of indispensable energy of society.The information demonstration providing according to USDOE, the oil of whole world consumption every day in 2006 reaches 3,500,000,000 gallons.In these oil, have 60 percent by marine transportation, to arrive destination, unfortunately, oil spill accident but fails thoroughly to avoid.Nineteen ninety to 1999, year during the decade every annual had the crude oil of 150,000 tons to flow in ocean all over the world.This situation is particularly serious in calendar year 2001, and 5 oil spill events have occurred in one week at that time unexpectedly.Along with the development of technological means, VLCC is not that unique arch-criminal that crude oil is revealed occurs yet.The danger that petroleum pipeline, offshore drilling platform, offshore petroleum store and oil plant all exists generation crude oil to reveal under water.After oil at sea leaks, oil spilling cleaning work just becomes the approach that alleviates Oil spills harm.Be proven, the nonwoven oil absorbent packet that is packaged with novel absorption material ZIF-8 in the present invention can effectively adsorb oil slick, alleviates and remove Oil spills on sea, to the sea produced pollution, to have high environmental significance.
Summary of the invention
For realizing technical scheme provided by the present invention, be:
With hydro-thermal method, prepare ZIF-8 porous adsorbing material, through washing fully, purify, after activation, adopt the method for heat bonding, be packaged in nonwoven, be made into novel nonwoven oil absorbent packet.
Through adsorption experiment, show, ZIF-8 porous adsorbent tactical rule prepared by this method, pore capacities is large, and nonwoven oil absorbent packet is good to the absorption property of oil.
Wherein, the hydrothermal synthesis method of porous adsorbing material ZIF-8 is: by 0.210 gram of zinc nitrate, 0.060 gram of glyoxal ethyline is dissolved in 18 milliliters of N, in dinethylformamide, after within ultrasonic 10 minutes, making it dissolve, mixed solution is placed in to 20 milliliters of polytetrafluoroethylene (PTFE) reactors, and 140 ℃ are reacted 24 hours.Question response still is cooling, adopts water/ethanolic solution to wash resulting metallic organic framework sorbing material, 200 ℃ of dry for standby.
The preparation method of nonwoven oil absorbent packet: nonwoven is converted into suitable size, cuts redundance, adopt electric sealing machine by the opening heat bonding of nonwoven, to only surplus next opening, for loading ZIF-8 porous adsorbent.
The preparation of the nonwoven oil absorbent packet based on ZIF-8 sorbing material: take appropriate metallic organic framework sorbing material, and loaded in nonwoven oil absorbent packet, after filling finishes, adopt electric sealing machine by the openend heat bonding of nonwoven oil absorbent packet.
The using method of ZIF-8 nonwoven oil absorbent packet: in advance above-mentioned nonwoven oil absorbent packet is cleaned with the solvent (as methyl alcohol, water, n-hexane etc.) of particular polarity before use, and dried.When carrying out the experiment of oil absorption property, this nonwoven oil absorbent packet is directly positioned over to surface flotation to be had on the sample solution of oil, and it is adsorbed petroleum component.After adsorption process finishes, nonwoven oil absorbent packet is taken out, adopt centrifugal method, the oil sample that absorbent packet is adsorbed is separated, and oil sample, after purified treatment, can continue to use.In addition, the nonwoven oil absorbent packet based on ZIF-8 porous adsorbing material can be realized and reusing, and without further purification process.
In the present invention, nonwoven cloth material for the preparation of nonwoven oil absorbent packet is without any restrictions, therefore, can adopt the nonwoven through any base group modification or modification according to research needs and practical application, and by similar method, can prepare the nonwoven oil absorbent packet of other coated ZIF-8 adsorbents.
Not only manufacturing process is simple to adopt the prepared nonwoven oil absorbent packet of method of the present invention, making and use cost are minimized, and the oil adsorption effect to offshore floating is good, therefore, both can save certain equipment cost, time cost and human cost, also can effectively reclaim the oil that is adsorbed bag enrichment simultaneously, reduce Oil spills pollution on the environment, also realized to a certain extent the recycling that reclaims petroleum resources.
The specific embodiment
For better understanding the present invention, below in conjunction with embodiment, the present invention is done further and described in detail, but the scope of protection of present invention is not limited to the scope that embodiment represents.
Embodiment:
The ZIF-8 porous adsorbing material of preparing with hydro-thermal method, the method for employing heat bonding, is packaged in non-woven bag, is made into novel nonwoven oil absorbent packet:
The hydrothermal synthesis method of porous adsorbing material ZIF-8 is: by 0.210 gram of zinc nitrate, 0.060 gram of glyoxal ethyline is dissolved in 18 milliliters of DMFs, after within ultrasonic 10 minutes, making it dissolve, mixed solution is placed in to 20 milliliters of polytetrafluoroethylene (PTFE) reactors, and 140 ℃ are reacted 24 hours.Question response still is cooling, adopts water/ethanolic solution to wash resulting metallic organic framework sorbing material, 200 ℃ of dry for standby.
Nonwoven is converted into suitable size, and cuts redundance.Adopt electric sealing machine that the opening of nonwoven is thermally bonded to only surplus next opening.Take ZIF-8 porous adsorbing material prepared by 500g hydro-thermal method, and loaded in nonwoven " pocket ", and openend is adopted to use the same method and carry out heat bonding, obtained a kind of novel nonwoven oil absorbent packet based on ZIF-8 adsorbent.
