Abstract
The invention relates to a silicon dioxide modified activated carbon which is prepared from the following raw materials in parts by weight: 90-100 parts of activated carbon, 20-25 parts of silicon dioxide, 5-7 parts of alum, 7-9 parts of zeolite powder, 4-6 parts of nano kaolin, 4-6 parts of CuSO4, 6-8 parts of Fe(NO3)2, 3-5 parts of Blumea oil, 4-5 parts of modified kieselguhr and right amount of water. By modifying the activated carbon with silicon dioxide, the activated carbon has the advantages of favorable adsorption action, low cost and no toxicity, and can be easily regenerated; the added zeolite powder and nano kaolin can catalyze the decomposition of organic substances, resist bacteria, remove odor, absorb moisture and prevent mold; the Blumea oil can shed perfume, and has a protective action on the patients with asthma; and the alum, CuSO4 and Fe(NO3)2 can implement disinfection and purify water. The activated carbon has the advantages of simple technique, lower cost and favorable development prospects.
Description
Technical field
The present invention relates to a kind of modified function Material Field, relate in particular to a kind of silica modified active carbon and preparation method thereof.
Background technology
Air pollution at present has had a strong impact on people's productive life, so air cleaning has had to pay attention to.Adsorbent is often used in air cleaning, mainly contains activated alumina, active carbon, also has 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.Along with people improve constantly the requirement of quality of life, also need the adsorbent that provides useful to human body.
Summary of the invention
The object of the present invention is to provide a kind of silica modified active carbon and preparation method thereof.
Technical scheme of the present invention is as follows:
An active carbon, is characterized in that being made by the raw material of following weight portion: active carbon 90-100, silica 20-25, alum 5-7, zeolite powder 7-9, nano kaoline 4-6, CuSO4 4-6, Fe (NO3) 2 6-8, Blumea oil 3-5, modification infusorial earth 4-5, water are appropriate;
Described modification infusorial earth is made by the raw material of following weight portion: diatomite 140-150, alum 10-12, nano-sized carbon 1-2, coix seed oil 1-2, ascorbic acid 2-3, citric acid 1-2, sodium phosphate trimer 2-3, ginseng pulverate 2-3; Preparation method puts into calcining furnace by diatomite to calcine 3-4 hour at 540-560 ℃, takes out, and the hydrochloric acid solution of putting into 12-15% soaks 4-5 hour, filter and take out, use clear water cyclic washing, dry, be added to the water, simultaneously, add nano-sized carbon, ascorbic acid, citric acid, alum, grind and obtain slurry, spraying is dry, other residual components is mixed with dried powder, and grinding distribution evenly and get final product.
The preparation method of described silica modified active carbon, it is characterized in that comprising the following steps: silica, alum are pulverized, send in retort together with zeolite powder, at 700-800 ℃, 3-4 hour is processed in charing, takes out, and adds furnishing mud shape in suitable quantity of water together with active carbon, nano kaoline, CuSO4, Fe (NO3) 2, be heated to 70-80 ℃, grind 3-4 hour to obtain 250-350 order slurry, it is neutral with clear water, washing to pH value, dries; Mix and be uniformly dispersed and get final product with other surplus stocks.
Beneficial effect of the present invention
The present invention has used silica to carry out modification to active carbon, and suction-operated is good, and cost is low, nontoxic, and regeneration easily; Add zeolite powder and nano kaoline can catalyzing organic decomposition simultaneously, antibacterial and deodouring, moisture absorption, mildew-resistant; Can be scentetd by use Blumea oil, asthma is had to protective effect per capita simultaneously; By using alum, CuSO4, Fe (NO3) 2, can sterilize, purify water.Technique of the present invention is simple, and cost is lower, good development prospect.
