Abstract
A modified activated carbon air adsorbent is prepared from the following raw materials: by weight, 100-200 parts of activated carbon, 20-23 parts of clay, 2-3 parts of polyvinyl alcohol, 4-5 parts of rice husk, 8-10 parts of modified attapulgite, a proper amount of 10-15% hydrochloric acid and a proper amount of water. According to the modified activated carbon air adsorbent, the clay, the rice husk and the polyvinyl alcohol are roasted and then used as carriers to improve adsorption activity, and the raw materials are safe and free of production of harmful substances, can absorb sulfides, viruses, formaldehyde and other harmful substances in the air, and is suitable for air purification and detoxification in daily life. The modified activated carbon air adsorbent has the advantages of easily obtained raw materials, simple process, low cost, suitability for industrial production, and good application 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 modified activated carbon air adsorption agent 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.
