Abstract
The invention discloses low-ash ultrahigh-specific area active carbon, which is prepared from the following raw materials in parts by weight: 120-130 parts of bamboo charcoal, 10-14 parts of potassium hydroxide, 15-20 parts of bauxite, 4-6 parts of industrial aluminum fluoride, 4-6 parts of diatomite, 6-8 parts of sodium metasilicate, 7-9 parts of cactus extract, 4-5 parts of modified diatomite and a right amount of water. According to the invention, potassium hydroxide is used for modifying the active carbon, so that the obtained active carbon has well-developed pore structure, ultrahigh specific area and extremely high adsorption speed; meanwhile, natural alkaline ores, such as the bauxite, are also used, so that the active carbon has the effects of sulfur removal, bacteria adsorption and the like. The low-ash ultrahigh-specific area active carbon has good adsorption performance and electrochemical performance, and can be widely used in medical and military chemical protection, water purification, air purification, gas defense and the like.
Description
Technical field
The present invention relates to a kind of modified function Material Field, relate in particular to a kind of low ash content activated carbon with high specific surface area 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.
