Abstract
The invention relates to modified active carbon for mercury removing. The modified active carbon is prepared from the following raw materials, by weight: 80-90 parts of active carbon, 3-4 parts of milk protein, 6-8 parts of acrylonitrile, 1-2 parts of ammonium persulfate, 3-4 parts of a molecular sieve, 2-3 parts of gelatin, 8-10 parts of modified attapulgite, and a proper amount of water. According to the present invention, the modified attapulgite and the ammonium persulfate are added during the active carbon modification process so as to increase the absorption speed on mercury and provide characteristics of simple process and easy operation; compared with the absorption capacity of the conventional active carbon, the absorption capacity of the modified active carbon of the present invention is increased by more than one time; and the spray drying is adopted so as to increase the activity of the modified active carbon, improve the absorption efficiency and the absorption speed of the active carbon on mercury, and remove the low concentration mercury in the aqueous medium.
Description
Technical field
The present invention relates to a kind of method of modifying of nonmetallic ore, relate in particular to a kind of modified activated carbon of removing mercury and preparation method thereof.
Background technology
Along with scientific and technological development, the progressively construction of modernization industry, various chemicals are exploited, and have brought facility, simultaneously because chemicals has produced environment and the harmful material of human body, the problem that has also become people to have to face to people's life.
Current airborne pollutant is mainly the toxic and harmful producing in the gas that produces of industrial fuel burning, vehicle exhaust, production.It is mainly to contain a large amount of noxious materials in the sewage of industrial production discharge that water pollutes, and also has the sewage in people's life to produce a lot of harmful substances.In people's life, also have and many times need to remove toxin, such as air conditioning filter has a lot of bacteriums, toxin on the net, newly-decorated has the harmful substances such as formaldehyde, all needs to remove toxin.All remove at present toxin and often use adsorbent, mainly contain silica gel, activated alumina, active carbon, molecular sieve etc., also have in addition for certain compositional selecting absorption and the sorbing material of development.But the most adsorption capacity of these adsorbents is limited, need to study different adsorbents for different requirements, bring into play best effect.Meanwhile, find new raw material, to strengthen adsorption effect, cost-saving.
Summary of the invention
The object of the present invention is to provide a kind of modified activated carbon of removing mercury and preparation method thereof.
Technical scheme of the present invention is as follows:
Remove a modified activated carbon for mercury, it is characterized in that being made by the raw material of following weight portion: active carbon 80-90, milk protein 3-4, acrylonitrile 6-8, Ammonium Persulfate 98.5 1-2, molecular sieve 3-4, gelatin 2-3, attapulgite modified 8-10, water are appropriate; The described attapulgite modified raw material by following weight portion is made: live tropine 2-3, lanthana 1-2, chromium oxide 3-4, morpholine 1-2, water of attapulgite 120-130, jade powder 3-4, kaolin 8-10, crosslinking agent TAC1-2, aluminium hydroxide 8-10, zinc stearate 2-3, borax 1-2, titanium sulfate 14-18, crow is appropriate; Preparation method sends into attapulgite, jade powder, kaolin in calcining furnace, at 870-890 ℃, calcines 2-3 hour, takes out, spill crosslinking agent TAC, then put into suitable quantity of water and grind, regulating lapping liquid pH value is 4-5, grind 1-2 hour, obtain 100-150 order slurry, then regulate lapping liquid pH value for neutral, add other residual components, continue to grind, obtain 200-300 order slurry, spraying is dry, obtains.
The preparation method of the modified activated carbon of described removal mercury, it is characterized in that comprising the following steps: active carbon, milk protein, acrylonitrile, Ammonium Persulfate 98.5 are joined in suitable quantity of water, grind 1-2 hour, add again gelatin, molecular sieve, continue to grind 30-45 minute, then, spraying is dry, mixes and get final product with attapulgite modified.
Divide the beneficial effect of the invention
The present invention has added attapulgite modified, Ammonium Persulfate 98.5 in activated carbon modified process, has improved the speed of Adsorption of Mercury, and technique is simple, and convenient operation is compared adsorption capacity with traditional active carbon and is more than doubled; The present invention is spray-dried, and the activity of modified activated carbon increases, and can improve active carbon to the adsorption efficiency of mercury and speed, and can remove the low mercury of concentration in aqueous medium.
