Abstract
The invention provides rare-earth modified activated carbon. The rare-earth modified activated carbon is prepared from the following raw materials in parts by weight: 100-120 parts of activated carbon, 5-7 parts of polytetrafluoroethylene emulsion, 6-8 parts of montmorillonoid, 4-6 parts of polyvinyl alcohol, 4-7 parts of natural zeolite, 7-9 parts of rare-earth, 3-5 parts of sodium borate, 4-5 parts of modified diatomite and a proper amount of water. Through modifying the activated carbon by natural stone powder such as rare-earth, the activated carbon has functions of resisting bacteria, de-coloration, flocculation, ion exchange, releasing beneficial microelements, desulfuration and the like; through bonding the activated carbon by polymer compounds such as polytetrafluoroethylene, the activated carbon is not likely to disintegrate and is easy to recover; the iodine adsorption value and the methylene cyanine adsorption value of the activated carbon exceed the national wood water purification first-grade activated carbon standard value; furthermore, the rare-earth modified activated carbon is simple and effective, the sources of the raw materials are wide, the cost is low, the corrosion is low, and the environment pollution is less.
Description
Technical field
The present invention relates to a kind of modified function Material Field, relate in particular to a kind of rare earth modified active carbon 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 rare earth 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 100-120, ptfe emulsion 5-7, imvite 6-8, polyvinyl alcohol 4-6, natural zeolite 4-7, rare earth 7-9, borax 3-5, modification infusorial earth 4-5, water are appropriate;
