Abstract
The present invention relates to a kind of air cleaning material of long-acting removal organic polluter, its preparation method is will to be acidified or alkalization activated carbon poly-dopamine；Then the activated carbon of poly-dopamine modified lithium is added in the composite particles solution of silicon dioxide coated nano manganese dioxide, 5 hours of stirring at normal temperature, filters, a kind of air cleaning material of long-acting removal organic polluter is obtained after vacuum drying.Activated carbon is both as adsorbent in the present invention, again as the solidified carrier of warm catalyst nanocatalyst, the warm catalyst of nanometer is loaded on activated carbon securely by dopamine, avoid the migration and loss of nano-particle, it can be carried out under conditions of unglazed, with technique is simple, performance is long-acting, safety and environmental protection long-acting removal organic polluter performance.
Description
Technical field：
The invention belongs to environmental friendly material field, and in particular to a kind of air cleaning material of long-acting depollution thing, its
Preparation method is based on bionical polymeric chemical reaction method.
Technical background：
Organic pollution is generally acknowledged strong noxious material, and its murder by poisoning to human body has strong toxicity.In recent years, house fitting is made
Research into Indoor air organic pollution and harm to the human body turns into social concerns focus.Organic pollution is to health
Very harmful, harm, high concentration organic contamination will be produced to respiratory system by being more than 0.1mg/m3 than indoor air formaldehyde content
Thing has harm to nervous system, immune system, liver.
At present, the processing method of indoor orgnic compound pollution is mainly net using air purifying preparation, VMC and air
Change device purified treatment.For VMC and air purifier purified treatment, its middle organic contamination that effectively purifies the air of a room
Thing is mainly realized by scavenging material.The material for core master of removal organic polluter in current and VMC and air purifier
There is the activated carbon of absorption property or load the activated carbon of photocatalyst.The specific surface area of high grade activated carbon is very big by (up to 3000
Meters squared per gram), it is non-polar adsorbent, with very strong hydrophobicity, therefore activated carbon is to the apolar substance tool of benzene series species
There is good adsorptivity, but by adsorbing the characteristics of there is easy saturation and discharged again with the change of environmental condition.Due to mesh
The utilization ratio of preceding photocatalyst visible ray is very low, so the activated carbon for loading photocatalyst needs to provide ultraviolet light source apparatus, so
On the one hand the complexity and cost of device are improved, on the other hand artificial ultraviolet source can cause the dirt of another form
Dye.In addition, common activated carbon supported nano-particle easily comes off.Therefore from practical angle, sky is used as by the use of activated carbon
The performance that gas purification eliminates organic pollution with material needs further to optimize.
The content of the invention：
Technological deficiency in terms of to solve current activated carbon and photocatalyst removal organic polluter, the present invention provides a kind of long
Imitate the air cleaning material of removal organic polluter.
The purpose of the present invention is achieved through the following technical solutions：A kind of air cleaning of long-acting removal organic polluter is used
Material, is prepared by bionical polymeric chemical reaction method, comprised the following steps：
(1) 20 parts by weight are acidified or alkalization activated carbon is added in dopamine solution and reacted 20 hours, filtration drying is obtained
To the activated carbon of poly-dopamine modified lithium；
(2) 1 parts by weight manganese dioxide is put into by second alcohol and water according to volume ratio 1:In the dispersant of 9 compositions, stirring
30 minutes, the manganese dioxide solution that concentration is 1 g/l is obtained, tetraethyl orthosilicate is added；Tetraethyl orthosilicate and manganese dioxide
Mass ratio is 1：10.
(3) ammoniacal liquor regulation PH to 8.5 is added dropwise, under agitation, the sodium hydroxide that concentration is 0.1mol/L is added dropwise in filtering
Solution adjusts pH value to 12, continues to react 2h, obtains the composite particles solution of silicon dioxide coated nano manganese dioxide；
(4) activated carbon of above-mentioned (1) poly-dopamine modified lithium is added to (3) solution, 5 hours of stirring at normal temperature, filtered,
120 degrees Celsius of 12 hours of vacuum drying, obtain a kind of air cleaning material of long-acting removal organic polluter.
Further, step 1) in the concentration of used dopamine solution be 2g/L；
Further, step 3) in the mass fraction of used ammoniacal liquor be 10%；
The beneficial effects of the present invention are：Activated carbon is both as adsorbent in the present invention, and is catalyzed as nanometer temperature catalyst
The solidified carrier of agent, with technique it is simple, be easy to industrial advantage.Nanometer temperature catalyst catalyst in the present invention has normal
Temperature catalytic decomposition organic pollution is the effect of carbon dioxide and water, and the participation of no light requirement, nano-particle is difficult by firm load
Come off, collaboration acidifying or alkalization activated carbon absorption organic pollution performance, overcome the shortcoming of adsorption saturation, with it is long-acting,
The performance of safe and environment-friendly removal organic polluter.
Brief description of the drawings：
The process chart of Fig. 1 present invention；
Fig. 2 materials of the present invention remove effect of formaldehyde；
Fig. 3 materials of the present invention remove toluene effect.
Embodiment：
Embodiment 1：
1) 20 grams of acidifyings or alkalization activated carbon are added to 150 milliliters and contain reaction 20 hours in 2g/L dopamine liquid,
The activated carbon of poly-dopamine modified lithium will be obtained；
2) 1 gram of nano-manganese dioxide is put into the dispersant (volume ratio 1 of 150 milliliters of ethanol/waters:9) in, 30 points are stirred
Clock, adding 500 microlitres of tetraethyl orthosilicate, (mass ratio of tetraethyl orthosilicate and manganese dioxide is 1：10)；
3) 10wt% 5 milliliters of ammoniacal liquor is added dropwise, PH to 8.5 is adjusted, filters, under agitation, concentration, which is added dropwise, is
50 milliliters of 0.1mol/L sodium hydroxide solution, regulation pH value to 12 continues to react 2h, obtains silicon dioxide coated nano dioxy
Change the composite particles solution of manganese；
4) activated carbon of above-mentioned poly-dopamine modified lithium is added to 3) solution, 5 hours of stirring at normal temperature, filtered, 120 is Celsius
Degree 12 hours of vacuum drying, obtain a kind of air cleaning material of long-acting removal organic polluter.
Fig. 2 removes effect of formaldehyde figure for resulting materials, it can be seen that being compared with absorbent charcoal material, material of the present invention
Material is greatly improved except effect of formaldehyde.Fig. 3 removes toluene design sketch for resulting materials, it can be seen that this hair
Bright material is significantly better than normal activated carbon except toluene effect.
