Description
Technical field
The present invention relates to field of Environment Protection, particularly relate to the preparation method of a kind of modified activated carbon.
Background technology
At present, as economic develops rapidly, chemical enterprise also high speed development therewith, cause the use of chemicals to increase
Many, the situation of harmful substance contaminant water environment by all means is also increasing, had both affected environment, and had damaged again health of people.
And these pollutant kinds are various, this causes serious impact to the improvement of enterprise, too increases certain difficulty.At present for
Acidity of Aikalinity pollutes the mode being mostly to use chemistry neutralisation treatment, virtually to enterprise with certain economic loss, thus a kind of
Very popular by modified activated carbon.
Content of the invention
In order to overcome the defect of above-mentioned prior art, it is an object of the invention to provide the preparation side of a kind of modified activated carbon
Method.
The present invention takes techniques below scheme to realize: the preparation method of a kind of modified activated carbon, and it includes following
Step: take suitable raw material, through crushed after being dried, crosses 40 mesh sieves, obtains carbon powder；Adhesive, pressure is added in carbon powder
Activate after making type, obtain activated carbon；Activated carbon is pre-oxidized, obtains surface oxygen-content active charcoal；By oxygen-content active
Charcoal is put in potassium hydroxide solution, regulates PH to 7 ~ 9, takes out and is dried, obtain modified activated carbon after standing.
The preparation method of above-mentioned a kind of modified activated carbon, described raw material is the various carbonaceous material such as anthracite, coking coal.
The preparation method of above-mentioned a kind of modified activated carbon, described baking temperature is at 60 ~ 80 DEG C.
The preparation method of above-mentioned a kind of modified activated carbon, a length of 8 ~ 12h during described standing.
The preparation method of above-mentioned a kind of modified activated carbon, described activation temperature is 200 ~ 400 DEG C.
The method have the advantages that the present invention utilizes the mode of modification to increase the surface of activated carbon in sum
Long-pending, improve using effect in organic solvent for the activated carbon, add its activity, economic and practical, can be widely applied to water dirty
The advantages such as dye process.
Detailed description of the invention
A kind of preparation method of modified activated carbon, it comprises the following steps: take suitable raw material, through crushed after being dried,
Cross 40 mesh sieves, obtain carbon powder；In carbon powder add adhesive, compressing after activate, obtain activated carbon；To activity
Charcoal pre-oxidizes, and obtains surface oxygen-content active charcoal；Oxygen-content active charcoal is put in potassium hydroxide solution, regulates PH to 7 ~ 9, quiet
Postpone taking-up to be dried, obtain modified activated carbon.
The preparation method of above-mentioned a kind of modified activated carbon, described raw material is the various carbonaceous material such as anthracite, coking coal.
The preparation method of above-mentioned a kind of modified activated carbon, described baking temperature is at 60 ~ 80 DEG C.
The preparation method of above-mentioned a kind of modified activated carbon, a length of 8 ~ 12h during described standing.
The preparation method of above-mentioned a kind of modified activated carbon, described activation temperature is 200 ~ 400 DEG C.
The method have the advantages that the present invention has raw material sources in sum wide, can be recycled, reduce money
The advantages such as the waste in source, utilize modified mode to increase the surface area of activated carbon, improve activated carbon in organic solvent
Using effect, adds its activity, economic and practical, can be widely applied to water pollution process.
The above is embodiments of the invention, therefore all according to the construction described in the present patent application scope, feature and principle institute
The equivalence change done or modification, in the range of being all included in present patent application.
