Description
Technical field
The invention belongs to technical field of active carbon, and in particular to a kind of preparation method with magnetic tube shaped activated carbon.
Background technique
With person's improvement of living standard, the environmental consciousness of people is also increasingly stronger, discharge of the various countries to various harmful substances
Various stringent relevant laws and regulations are all formulated, especially to the sewage of discharge such as phenol, in the harmful substances and exhaust gas such as heavy metal
Sulfide and oxynitrides content have stringent regulation.Require waste water that we must be exceeded to dirt, exhaust gas
Carry out purified treatment.And with the raising of person's scientific and technological level, there has been proposed environmental consciousness material requirements to develop light pollution or nothing
Prepared by the material of pollution, processing, use and recovery technology.And tubulose active carbon has micropore and meso-hole structure, has higher
Reference area and a variety of functional groups, average pore diameter is smaller, by physical absorption, chemisorption and physical chemistry skin
Etc. modes in seawater, exhaust-gas treatment, solvent recovery, the fields such as Water warfare are widely applied.Thus tubulose active carbon is in ring
The application in guarantor field is increasingly by the attention of environmental worker
Bombax cotton is unicellular native cellulose fibre.Its wall by 64% cellulose, 13% lignin, 8.6% water,
The ash content of 1.4-3.5%, the water-soluble substances of 4.7-9.7%, the xylan of 2.3-2.5% and 0.8% wax composition.Wherein without
Machine ingredient is low and carbon content is high, is suitable for preparing tubulose active carbon.Since the kapok yield in China reaches, raw material obtains simple, wood
Cotton fiber has very thin cell wall, has the huge hollow region full of air, therefore have big specific surface area.It uses
Zinc chloride is pre-processed, so that tubulose active carbon has more bigger serface, is impregnated ferric trichloride, is passed through carbonization-activation tubulose
Activated carbon supported Fe3O4With magnetism.It can control the direction of motion of micro machine, can also recycle, avoid secondary pollution.
Currently, it is many about the relevant report for using bombax cotton to do active carbon, but had using bombax cotton preparation
There is presently no see for the report of magnetic tubulose active carbon.
Summary of the invention
The object of the present invention is to provide magnetic tubulose active carbon of a kind of tool and preparation method thereof, it is easy to get with cheap
Bombax cotton loads Fe as absorbent charcoal material3O4, magnetic tube shaped activated carbon is prepared, can reach difficult by magnetic guiding
Cleaning treatment is carried out with close Polluted area, and can be recycled after treatment by external magnetic field, it is avoided to cause two
Secondary pollution.
To achieve the above object, the technical solution adopted by the present invention is that:
A kind of preparation method having magnetic tubulose active carbon, the described method comprises the following steps:
(1) bombax cotton is immersed in the mixed solution of ferric trichloride and zinc chloride, cleaning, drying after the completion of impregnating；
(2) step (1) treated bombax cotton is cleaned and dried, is then sintered under nitrogen protection, obtains sintered sample；
Further, the molar concentration rate of ferric trichloride and zinc chloride is in the mixed solution of the ferric trichloride and zinc chloride
1:1.
Further, bombax cotton is immersed in 48 h in the mixed solution of ferric trichloride and zinc chloride.
Further, sintering temperature is 500-600 DEG C in step (2), sintering time 20-60min.
Further, cleaning way is with deionized water eccentric cleaning 2-3 times in step (1).
Further, drying temperature is 60 DEG C in step (1), drying time 48-72h.
Compared with prior art, main advantages of the present invention: raw material prepared by the present invention is commonly easy to get, low in cost, system
Standby process is simple, environmentally protective.During the preparation process, the active carbon and ferroso-ferric oxide for obtaining high-specific surface area are uniformly distributed
On the carbon pipe of bombax cotton, to obtain having magnetic tubulose active carbon, make with excellent absorption property and circulation
With performance, there is potential application value in environment protection field.

Specific embodiment
In order to make content of the present invention easily facilitate understanding, the present invention will be further described for following instance, but
It is not used to limit the scope of the present invention.
Embodiment 1
Bombax cotton surface spray plasma is subjected to hydrophily processing first.By the liquor ferri trichloridi and 1mol/L of 1mol/L
Liquor zinci chloridi be blended in 50mL beaker, impregnate 48h, take out kapok clean 2-3 times with deionized water, put drying box do
It is dry.Dry sample is sintered under nitrogen protection afterwards, 550 DEG C of heat preservation 30min are warming up to 10 DEG C/min, is down to room temperature taking-up
Sample obtains and has magnetic tubulose active carbon.
Spread out to the magnetic tubulose active carbon of tool obtained by above-described embodiment 1 using scanning electron microscope (SEM), X-ray
The instruments such as instrument (XRD), BET test are penetrated to analyze product.
Fig. 1 is load Fe3O4Tubulose active carbon SEM figure, it can be seen that carbon pipe surface has many Fe3O4 particles.
Make it have magnetism.
