Abstract
The present invention relates to the Nanoscale Iron synthesized by Green Manufacturing Technology-polyphenol to chelate particle.For example, the present invention relates to the Nanoscale Iron formed by the plant extract solution-application of polyphenol chelating particle and these nano particles in the pollutant of removal underground water and other polluted places.In some embodiments, the present invention includes making and using the Nanoscale Iron-polyphenol chelating particle method formed using Green Chemical Technology.
Description
Technical field
The present invention relates generally to the novel nano of induction biosynthesis iron-polyphenol chelating particle (Fe-P NPS), can be used for water and
Groundwater treatment, soil and groudwater remediation, air pollution processing, medical diagnostic tests, medical material, targeted drug conveying,
Catalytic chemistry synthetic reaction, contamination control or monitoring device, fuel cell or electronic equipment.
Background technique
Conventional water treatment technology includes such as biochemical reaction, chemical coagulation, flocculation, chemical oxidation, carbon adsorption, light degradation
Deng.Absorption and flocculation can handle sizable flow, produce the water of high quality.The harmful substances such as chemical oxidation are not generated
Effluent.The absorption in water process is studied with a variety of materials such as clay, flyash, active carbon, charcoal, wheat straws.Tradition
Coagulant and flocculant be inorganic salts (such as Al2(SO4)3·18H2O、FeSO4·7H2O、FeCl3·6H2O), inorganic polymer
Flocculant (such as bodied ferric sulfate), Syn-Organic flocculants (such as polyacrylamide) and natural macromolecule flocculating agent are (such as
Chitosan).Cohesion and flocculation occurred in the continuous stage, their target is to overcome equilibrant force between stable suspersion particle, allowed
The growth of particles collision and floccule.However, the shortcomings that flocculant, is that sludge quantity is big, removes pollutant low efficiency, is at high cost.It is special
It is not that Syn-Organic flocculants can cause to damage to organism DNA.Therefore have very to the flocculant of synthesis green high-efficient
Big necessity.Referring to: Forgacs, E.；Cserh á ti, T.；Oros, G., Environment International 2004,

Summary of the invention
The present invention relates to make and use to chelate particle and its system by Nanoscale Iron-polyphenol that green chemical synthesis technology is formed
Preparation Method.For example, the present invention relates to the Nanoscale Iron formed by plant extract solution chelating particle and these Fe nanometer particles
Purposes in terms of the pollutant in removal industrial wastewater and underground water.
Compared with physics, chemistry and microbial process, the present invention is without using toxic chemical as reactant, organic solvent
Or not biodegradable stabilizer, therefore do not have potential danger to environment and biosystem.In addition, this method does not need
The condition of complicated control or very standard, keeps them comparatively inexpensive.
In one aspect, the present invention provides prepare Nanoscale Iron-polyphenol chelating particle method.In some embodiments
In, the method includes providing the iron ion of dissolution；Plant extracts is provided, the plant extracts includes chelating agent, polyphenol
Or natural solvent or surfactant；And the iron ion of dissolution and plant extracts are combined to produce Nanoscale Iron-polyphenol and chelate
Particle.For example, the iron ion of dissolution can be provided by dissolving molysite in water.For example, dissolved iron in water can be passed through
Chelate provides the iron ion of dissolution.For example, the dissolution offer of iron ion, the offer of plant extracts or dissolution iron ion and
The combination of plant extracts can be carried out with preparing nano particle under 100 degrees Celsius.For example, can be can be in the mankind for room temperature
Temperature in the range of enduring.For example, temperature be greater than or equal to water freezing point and less than or equal to water freezing point and be lower than or wait
Room temperature is considered in the temperature of the maximum temperature of earth surface Lock-in.For example, room pressure can be greatly
In or equal to the pressure of minimum value that occurs on earth surface, less than or equal to the maximum value occurred on earth surface.Nanoscale Iron-
Polyphenol chelating particle can effectively concentration be present in application, such as water and wastewater treatment, soil and groudwater remediation, air
Pollution processing, medical diagnosis test, medical material, targeted drug conveying, the catalysis of chemosynthesis reaction, contamination control or monitoring
The analysis of device, fuel cell or electronic equipment.Nanoscale Iron-polyphenol chelating particle can have about 5 and about 500 nanometers
Average diameter.Chelating agent, plant extracts can be mentioned by the source of such as eucalyptus, rosemary, Salvia japonica, tealeaves and combinations thereof
For.Here, unless otherwise indicated, the source of plant extracts should be understood to refer to product or substance and source, with source phase

The research of dyestuff in Nanoscale Iron-polyphenol chelating composition granule removal water
Using 100 grams of folium eucalyptis as raw material, 500 milliliters of meter Ye Shui 1h are added at 80 DEG C, plant leaf extract are prepared, through precipitating
After 1h, vacuum filter.By the way that 16.23 grams of ferric trichloride is added in 1L meters of water, it is prepared for 0.10 μm of traditional flocculant
FeCl3, and add it in 0.1 μm of liquor ferri trichloridi, volume ratio 1: 2.The formation of Fe-P NPS is mark with black
Will.The chalybeate amount in Fe-P NPS is reported herein.
It is dissolved in 200 milliliters of milli Q water with 260 milligrams of acid black 1s 94, prepares the solution of acid black 1 containing 1.3g/L 94.It will
In a series of (0.1,0.2,0.3,0.6,0.9 and 1.2 milliliter) addition 50 milliliters of water of bottle of volume Fe-P NPS, and with 1 milliliter
Dye solution contact, dye solution have scheduled initial dye concentration.Bottle is sealed and is gently shaken, and is then maintained at different
Temperature (278,298,310K) 24 hours.Suspension pH value is adjusted by the way that 1 milliliter of HCl or NaOH is added.With Perkin-Ai Ermo
Ultraviolet-uisible spectrophotometer λ 18 measures the suction of absorption maximum (578nm) supernatant of dyestuff in the range of 200~800nm
Luminosity.
By changing Fe-P NPS and FeCl in dye solution3Dosage, study the removal efficiency of dyestuff.With flocculant
The increase of dosage, dyestuff removal efficiency increase.Under the conditions of natural subsidence, Fe-P NPS and FeCl3Optimum dosage be 0.9
Milliliter, maximum dyestuff removal rate is respectively 80.5% and 62.4%.Experiments have shown that when using same amount of FeCl3When, Fe-P
NPS is more universal to the removal effect of dyestuff.
