Abstract
The invention discloses a kind of methods in regulation active fruit shell carbon aperture to be bombarded using active fruit shell carbon as raw material by different laser energies, obtains the active fruit shell carbon of different pore size size, and have high specific surface area；Raw material prepared by the present invention is commonly easy to get, low in cost, and preparation process is simple, environmentally protective, and obtained active fruit shell carbon has excellent absorption property, has potential application value in environment protection field.
Description
Technical field
The invention belongs to technical field of active carbon, and in particular to a method of regulation active fruit shell carbon aperture.
Background technique
Active carbon is mainly with sawdust, and various shells (coconut husk, apricot shell, walnut shell etc.), coal and petroleum coke are contour carbon containing
Substance is raw material, processes to obtain with flourishing porous structure, excellent absorption property, good chemical inertness by heat chemistry
And the carbon material adsorbing material of the advantages that electric conductivity, it is widely used in food, pharmacy, chemical industry, environmental protection, military and chemical contamination thing
Therefore the fields such as relief, it is product indispensable in the national economic development and people's life.Economic continuous development and the people
Living standard steps up so that the application of active carbon is increasingly valued by people, and output constantly increases.Absorption is net
Change is the most important aspect of activated carbon application, such as to the food generated by biofermentation or synthetic technology, drug and health care
The recycling and purifying of the decolorizing and refining of product, organic solvent and oil product oil gas, drinking water and wastewater purification, the chemicals of burst
Or heavy oil adsorbs first aid etc. to rivers pollution of waterhead, meanwhile, the thermal inertia and chemical inertness of active carbon make it with good
Good regenerability, can be recycled, and reduce operating cost, economize on resources.
Active carbon is as porous adsorbing material, specific surface area, pore volume and aperture size influence absorption property it is important because
Element.Regulate and control active fruit shell carbon aperture by different laser energy bombardment up to size, obtains the active carbon of bigger serface.
Currently, there are many relevant report about regulation activity charcoal aperture, but use different laser bombardments regulation shell living
The report in property charcoal aperture is current or fewer.
Summary of the invention
The object of the present invention is to provide a kind of methods in regulation active fruit shell carbon aperture, are bombarded with different laser energies
Active fruit shell carbon carrys out regulation activity charcoal pore size, active carbon is prepared, and has higher specific surface area, has higher
Adsorption capacity.
To achieve the above object, the technical solution adopted by the present invention is that:
1, a kind of method in regulation active fruit shell carbon aperture, it is characterised in that: the described method comprises the following steps:
(1) active fruit shell carbon is placed on glass slide and is tiled；
(2) it by step (1) tiled active fruit shell carbon, is bombarded with different laser energy, by adjusting laser energy tune
Whole obtained activated carbon surface pore size.
Further, the energy of laser bombardment described in step (2) is 60-170 μ J.
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, regulate and control active fruit shell carbon pore size, there is high specific surface area, tool
There is excellent absorption property and performance is recycled, has potential application value in environment protection field.
Figure of description
Fig. 1 is that active fruit shell carbon is not schemed by the SEM of laser bombardment；
Fig. 2 is that active fruit shell carbon is schemed by the SEM after laser bombardment.
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
Active fruit shell carbon is placed on glass slide first and is tiled.Laser energy is regulated, we take 5 kinds of different laser energies
Carry out bombardment active fruit shell carbon, respectively 60 μ J, 90 μ J, 120 μ J, 140 μ J, 170 μ J.Shell after being bombarded is living
Property charcoal.
The resulting active fruit shell carbon of above-described embodiment 1 analyzes product using scanning electron microscope (SEM).
Fig. 1 is that active fruit shell carbon is not schemed by the SEM of laser bombardment.As can be seen that active fruit shell carbon surface micropore is relatively more,
Middle macropore is less.
Fig. 2 is that active fruit shell carbon is schemed by the SEM after laser bombardment.It can be seen that the active fruit shell carbon after laser bombardment
Surface increases many middle macropores, its specific surface area can be improved.
Although specific embodiments of the present invention have been described above, those familiar with the art should be managed
Solution, we are merely exemplary described specific embodiment, rather than for the restriction to the scope of the present invention, it is familiar with this
The technical staff in field should be covered of the invention according to modification and variation equivalent made by spirit of the invention
In scope of the claimed protection.
Claims (2)
1. a kind of method in regulation active fruit shell carbon aperture, it is characterised in that: the described method comprises the following steps:
1) active fruit shell carbon is placed on glass slide and is tiled；
2) it by the tiled active fruit shell carbon of step 1), is bombarded with the laser of different-energy, by adjusting laser energy tune
Whole obtained activated carbon surface pore size.
2. a kind of method in regulation active fruit shell carbon aperture according to claim 1, it is characterised in that: described in step 2
The energy of laser bombardment is 60-170 μ J.
