Abstract
The invention discloses compound membrane for water treatment of a kind of graphene oxide and preparation method thereof, have three-layer composite structure, are high-molecular porous pretreatment layer, graphene oxide activity purifying layer and high-molecular porous materials for support layer successively from top to bottom.Preparation method：Graphene oxide, thermal plastic high polymer adhesive, other active materials and auxiliary agent are pre-configured to sol ink, sol ink is fully dispersed, then sol ink is carried on supporting layer by the method for coating again, then it is then covered with high-molecular porous pretreatment layer, after drying to be drained off, using hot-forming.The present invention can effectively filter out microorganisms, the organic matters such as heavy metal, bacterium in water etc.；GO particulate matters can be wrapped up less to keep the filtering efficiency of GO, thermal plastic high polymer binder can bond pretreatment layer and support layer material simultaneously simultaneously, film material is formed, and then GO is avoided to be lost in, can be widely applied in all kinds of water purification installations and engineering of water treatment equipment.
Description
Technical field
The invention belongs to Water warfare fields, specifically, being related to a kind of compound membrane for water treatment of graphene oxide and its preparation
Method.
Background technology
Water is resource most valuable on the earth, closely bound up with the health of the mankind.Increase with earth population and work
Industry produces movable increase, and various water pollution problems constantly threaten the health of the mankind.In China, drinking water pollution problem is also chosen
It fights heavy, such as heavy metal, disinfection by-products, incrustation scale, the potential risk of antibiotic micropollutants are huge.Such as Guangzhou change institute
The first antibiotic whole nation usage amount that Ying Guangguo researcher discloses shows have 3800 tons of antibiotic to be arranged every year with discharge capacity inventory
It puts, wherein 46% is thrown into water body, causes potential huge drinking water pollution risk.Obtain the technique skill of clean water resources
Art is all essential key technology in the whole world.
In recent years, since China's water pollution is serious, the health perception of society generally enhances, and China's water purification industry is quick
Development, market potential are huge, it is contemplated that will be up to 400,000,000,000 yuan, media has said this is last block of 21 century household electric appliances
Cake.The happy health data prediction in, China's purifier market scale will be up to 33,600,000,000 yuan within 2017, and continuous 6 years speedups are more than
20%.The governments at all levels of central and local governments are acutely aware of development direct drinking water purification core technology to ensureing people's drinking water health
Importance.2015, State Council formally promulgated《Water prevention and cure of pollution action plan》(promulgated by the State Council (2015) 17), referred to as " water ten
Item ", strategic support develop drinking water treatment research of technique research and development.
Current reverse osmosis purified water technology is micro- because that can filter out most heavy metals, antibiotic, microorganism in water body etc.
Pollutant and used by a large amount of manufacturers, market accounting has been more than 70%.But reverse osmosis membrane purifier is because of the waste water of flood tide
It discharges and is often denounced by consumers in general, it is vigorous to develop Novel water-purifying materials demand thus.
After graphene was successfully removed from 2004, because making it in numerous areas with a series of excellent characteristic
All have broad application prospects, such as RF transistors, transparent conductive film, lithium ion battery, ultracapacitor, new catalytic
Agent, thermo-electric device, solar cell, sensing and detection etc..Atomic layer level thickness that graphene has, high mechanical properties, chemistry are steady
Qualitative good, good conductivity, the specific surface of superelevation, and its derivative (graphene oxide, fluoride, nitride etc.) surface contains
The abundant functional group having makes graphene and its derivative and related graphene composite material have stronger selective absorption
Ability；These characteristics make graphene and its composite material have vast potential for future development in water treatment applications.Graphite oxide
Alkene (GO) can not only adsorb the pollutants such as organic solvent, the heavy metal in water well, be alternatively arranged as catalyst carrier, catalytic water
The degradation of middle pollutant.In addition the interlayer spacing between graphene can regulate and control so that pure water by by be isolated it is each
Cationoid.Since 2010, grapheme material started that rapid growth trend is presented in the correlative study of water treatment applications.Especially
Its recent years, a series of high-caliber research papers show Graphene derivative and its composite material as filter layer in Shui Chu
It ought to use and show remarkable development prospect.But compared to graphene other application, graphene water treatment applications this
The exploitation of a little technical matters also just starts to grow up in recent years, is also in primary research stage, relevant industrialization skill at present
Art research has yet to begin starting.Especially graphene oxide is because the problems such as particle is small, easy leakage hinders it and produced in water process
Application in industry.
Invention content
In order to effectively solve the above problems, the present invention provides a kind of compound membrane for water treatment of graphene oxide and its preparation sides
Method.
To achieve the above object, the present invention adopts the following technical scheme that：
A kind of compound membrane for water treatment of graphene oxide has three-layer composite structure, is high-molecular porous successively from top to bottom
Pretreatment layer, graphene oxide activity purifying layer and high-molecular porous materials for support layer.
In the above-mentioned compound membrane for water treatment of graphene oxide, the aperture of the high-molecular porous pretreatment layer exists
Between 2-10 microns, the thickness of high-molecular porous pretreatment layer is at 0.2-2 millimeters.The effective solid filtered out in water body is not
Tolerant, particulate matter, colloid etc..
In the above-mentioned compound membrane for water treatment of graphene oxide, the high-molecular porous pretreatment layer or macromolecule
The material of porous material supporting layer is PP, PE or nylon.
