Abstract
A citric acid modified activated carbon material is prepared from the following raw materials: by weight, 90-100 parts of activated carbon, 30-34 parts of citric acid, 10-12 parts of white vinegar, 8-12 parts of calcium chloride, 12-14 parts of silica gel, 8-10 parts of modified attapulgite and a moderate amount of water. The citric acid, acetic acid and other acidic raw materials are added to the modified activated carbon, so that on the one hand, tap water becomes weak acidic, and the modified activated carbon has the effects of sterilization, disinfection, face beautifying and skin care, and on the other hand, the adsorption capacity of the activated carbon is maintained for tap water purification; the spray-dried modified attapulgite is added into the modified activated carbon, so that the adsorption effect of the modified activated carbon is stronger; the preparation method of the modified activated carbon is novel in process, is simple and easy, is low in cost, and has important environmental protection properties and excellent market prospects.
Description
Technical field
The present invention relates to a kind of method of modifying of nonmetallic ore, relate in particular to a kind of citric acid-modified absorbent charcoal material 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 to people's life, simultaneously because chemicals has produced environment and the harmful material of human body, the problem that has also become people to have to face.
Current airborne pollutant is mainly the toxic and harmful produced 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.Also have and many times need to remove toxin in people life, such as air conditioning filter has a lot of bacteriums, toxin on the net, newly-decorated has the harmful substance 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., the sorbing material of developing for certain compositional selecting absorption in addition in addition.But the most adsorption capacity of these adsorbents is limited, need to study different adsorbents for different requirements, bring into play best effect.Simultaneously, 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 citric acid-modified absorbent charcoal material and preparation method thereof.
Technical scheme of the present invention is as follows:
A kind of citric acid-modified absorbent charcoal material is characterized in that being made by the raw material of following weight portion: active carbon 90-100, citric acid 30-34, light-coloured vinegar 10-12, calcium chloride 8-12, silica gel 12-14, 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; The preparation method sends into attapulgite, jade powder, kaolin in calcining furnace, and under 870-890 ℃, calcining 2-3 hour, take out, spill crosslinking agent TAC, then put into suitable quantity of water and grind, regulating the lapping liquid pH value is 4-5, grind 1-2 hour, obtain 100-150 order slurry, then regulate the lapping liquid pH value for neutral, add other residual components, continue to grind, obtain 200-300 order slurry, spray-drying, obtain.
The preparation method of described citric acid-modified absorbent charcoal material, it is characterized in that comprising the following steps: active carbon and citric acid, light-coloured vinegar, calcium chloride, silica gel are added in suitable quantity of water, be heated to 85-90 ℃, grind 3-4 hour, obtain 200-400 order slurry, size mixing material PH for neutral, and spray-drying, mix and get final product with attapulgite modified.
Divide the beneficial effect of the invention
Super-hydrophobic activated carbon modified material of the present invention contains dimethyl-silicon wet goods hydrophobic ingredient, made up the easy moisture absorption of porous carbon material under high humility, can be afraid of by water erosion equipment for some, as air-conditioning filter net, be easy to reclaim, but the repetitive cycling utilization, not only saved industrial cost, and more industrial applications is laid a good foundation.
Modified activated carbon of the present invention has added the acid materials such as citric acid, acetic acid, can, by running water weak acid, have the effect of sterilizing, beauty and skin care on the one hand; Continue on the other hand to have retained the adsorption capacity of active carbon, make tap water purifying; Also have the present invention to add spray-dried attapulgite modified, adsorption effect is stronger; This method new technology, simple, cost is low, has the important feature of environmental protection and splendid market prospects.
