Technical field
The invention belongs to the active carbon field, more specifically relate to a kind of supported ion liquid active and its preparation method and application.
Background technology
Active carbon is flourishing because of pore structure, specific area is large, surface functional group is abundant, content of ashes is low, chemical property (acidproof, alkaline-resisting, heat-resisting) is stablized, mechanical strength is high, water insoluble and the advantages such as organic solvent, renewable recycling, is widely used in administering the pollutants such as organic and inorganic in the environment such as water body, air, soil, bacterium and dust.But since activated carbon variety few, with low content of technology, lack the high-quality special-purpose activated charcoal of functionalization, the higher level application of marching toward of restriction China activated carbon industry.With activated carbon modified processing, develop can carry out efficiently pollutant, the functional activity charcoal of deep purifying, be to reduce the active carbon use cost, enlarge its scope of application, improve the effective way of its utilization ratio, be the direction of activated carbon industry future development.
Ionic liquid refers to be also referred to as low temperature molten salt in room temperature or near presenting salt liquid, that be comprised of zwitterion fully under the room temperature.Its developing history can be traced back to 1914, it generally is comprised of organic cation and inorganic anion, and is different with typical organic solvent, and ionic liquid generally can not become steam, so in the chemical experiment process, can not produce the pernicious gas that atmosphere is polluted, and easy to use.Can cause that more the chemist is interested to be that ionic liquid can repeated multiple timesly use.In addition, do the process that catalyst also can accelerate chemical reaction with ionic liquid.The chemist of British Petroleum Company is blue saying not, if British Petroleum Company adopts ionic liquid in chemical process, then the large organic solvent of volatility capable of reducing using reduces the pollution to environment, reduces the generation of refuse.
The industrial waste gas that volatile organic contaminant mainly produces from fuel combustion and communications and transportation, vehicle exhaust, photochemical pollution etc.; At the indoor smog that then mainly comes the combustion products such as spontaneous combustion coal and natural gas, smoking, heating and the cooking etc., the discharging of building and ornament materials, furniture, household electrical appliance, cleaning agent and human body itself etc.In the interior decoration process, VOC is mainly from paint, coating and adhesive.When the concentration of volatile organic contaminant in the room surpasses when a certain amount of, at short notice people will feel to have a headache, feel sick, the symptom of vomiting, limbs fatigue; Can twitch when serious, stupor, failure of memory.Can produce larger harm to liver, kidney, brain and the nervous system of human body.Volatile organic contaminant has caused that in recent years various countries pay attention in the room.
