Abstract
A zirconium oxide modified activated carbon adsorbent for removing phosphates is prepared from the following raw materials: by weight, 100-120 parts of activated carbon, 3-4 parts of zirconium n-propoxide, 5-6 parts of sodium tripolyphosphate, 3-4 parts of sodium alginate, 1-2 parts of polyethylene terephthalate, 3-4 parts of octadecyl trimethyl ammonium chloride, 8-10 parts of modified attapulgite and a proper amount of water. The zirconium oxide modified activated carbon adsorbent using the zirconium n-propoxide for modification of the activated carbon can be applied to adsorption removal of the phosphates in water bodies, and has a strong adsorption property; the polyethylene terephthalate and other additives are also added to make the activated carbon be uniformly and stably dispersed in the water, thereby the adsorption effect is better; the zirconium oxide modified activated carbon adsorbent has the advantages of simple preparation, easily obtained materials, simple operation, obvious treatment effect, and good economic and environmental benefits.
Description
Technical field
The present invention relates to a kind of method of modifying of nonmetallic ore, relate in particular to a kind of zirconia modified activated carbon dephosphorization hydrochlorate adsorbent 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 zirconia modified activated carbon dephosphorization hydrochlorate adsorbent and preparation method thereof.
Technical scheme of the present invention is as follows:
A kind of zirconia modified activated carbon dephosphorization hydrochlorate adsorbent is characterized in that being made by the raw material of following weight portion: active carbon 100-120, zirconium-n-propylate 3-4, sodium phosphate trimer 5-6, sodium alginate 3-4, PETG 1-2, OTAC 3-4, attapulgite modified 8-10, water are appropriate; The described attapulgite modified raw material by following weight portion is made: attapulgite 120-130, sodium carbonate 3-4, bauxite 5-6, vanadium boride 1-2, jade powder 3-4, ferrous sulfate 1-2, titanium sulfate 14-18, active carbon 12-14, medical stone 2-3, lanthana 1-2, chromium oxide 3-4, morpholine 1-2, water are appropriate; Attapulgite, bauxite, jade powder, active carbon are sent in calcining furnace, and under 850-870 ℃, calcining 4-5 hour, take out, putting into suitable quantity of water grinds again, regulating the lapping liquid pH value is 4-5, grinds 1-2 hour, obtains 100-150 order slurry, regulate again 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 zirconia modified activated carbon dephosphorization hydrochlorate adsorbent, it is characterized in that comprising the following steps: all raw materials are added in suitable quantity of water, be heated to 85-95 ℃, grind 2-3 hour, obtain 100-150 order slurry, regulating the lapping liquid pH value is that 4-5 continues to grind, and obtains 250-350 order slurry, and it is neutral regulating the lapping liquid pH value, spray-drying, send in heat-treatment furnace, process 3-4 hour under 310-330 ℃, obtain;
Divide the beneficial effect of the invention
