Abstract
Modified activated carbon for removing organic pollutants is prepared from the following raw materials: by weight, 80-90 parts of activated carbon, 6-8 parts of chitosan, 3-4 parts of Arabic gum, 1-2 parts of sodium alginate, 30-34 parts of sepiolite, 12-14 parts of zeolite, 8-10 parts of modified attapulgite and a proper amount of 20-25% hydrochloric acid and water. The modified activated carbon prepared by the method is used as an adsorbent, at the same time, the sepiolite, the zeolite and other substances with strong adsorption ability are added into the modified activated carbon, and the modified activated carbon can be used for removing the organic pollutants in a water treatment process, has the advantages of high purification capacity and long service life, and especially can solve the problem that water treatment methods in the prior art have poor operability on water polluted by endocrine disruptors of high concentration of phenols.
Description
Technical field
The present invention relates to a kind of method of modifying of nonmetallic ore, relate in particular to a kind of organic pollution modified activated carbon and preparation method thereof that removes.
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 super-hydrophobic activated carbon modified material and preparation method thereof.
Technical scheme of the present invention is as follows:
A kind of organic pollution modified activated carbon that removes is characterized in that being made by the raw material of following weight portion: active carbon 80-90, shitosan 6-8, Arabic gum 3-4, sodium alginate 1-2, sepiolite 30-34, zeolite 12-14, attapulgite modified 8-10,20-25% hydrochloric acid is appropriate, water is 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.
