Description
Technical field
The invention belongs to indoor air purification fields, and in particular to a kind of composition for administering gaseous acrolein.
Background technique
Methacrylaldehyde is all earliest putative carcinogen.According to Environmental Protection Agency USA (USEPA) estimate, nearly half by
Cancer morbidity caused by toxic, hazardous air pollutants is mainly due to caused by the pollutant of automotive emission.Its
In, the vehicular emission total amount of methacrylaldehyde is 1.65 × 104t.Methacrylaldehyde etc. because its with irritation, toxic, carcinogenicity and
Mutagenicity and be concerned.In cigarette mainstream flue gas, methacrylaldehyde burst size is 50~140 μ g/ branch, and methacrylaldehyde is lived without being metabolized
Change, adduction directly can occur with DNA, 2 kinds of cross-linked structures of DNA-DNA and DNA- protein be formed, to show different causes
Mutability.It is largely trapped in into intracorporal methacrylaldehyde and directly invades position, bronchial mucosa and muscle layer can be stimulated, make glutinous egg
Bai great Liang is generated, and the methacrylaldehyde sucked in lung can cause pulmonary edema and bronchial epithelial cell damage.
As it can be seen that the biological exposure limits for establishing methacrylaldehyde in the flue gas of public arena are the important of stopping smoking and maintaining healthy
Behave.GB/T 27630-2011 defines the concentration≤0.05 (mg/m of methacrylaldehyde in in-vehicle air3), to avoid indoor and vehicle
The harm of methacrylaldehyde in interior air, domestic and foreign scholars are dedicated to the improvement and elimination of methacrylaldehyde.According to the literature, mercaptan, tertiary fourth
Though the fragrant acid of base mattress and hydralazine can be used as propylene aldehyde scavenger, majority is organic solvent, and volatile and smell can pollute ring
Border；When adjusting pH to 7.4 with phosphate buffer solution for 20 DEG C, cysteine and glutathione and methacrylaldehyde can generate stable
Addition product；With methacrylaldehyde effective scavenger that addition forms cyclic adduct and methacrylaldehyde can occur for ascorbic acid；In nothing
0.05mmol/L hydralazine processing 30min is added in cell system can cut down 92% methacrylaldehyde；0.05mmol/L is added
Nepresol processing 30min can be reduced the content of propylene aldehyde to 1%.Based on generating addition product or adduction with acrolein reaction
Object has the effect of certain removing methacrylaldehyde, but severe reaction conditions, at high cost.Develop it is a kind of it is efficient, quick, convenient, low at
The new material and technical method of this improvement methacrylaldehyde are the research hotspots that confined space removes air pollution source.

In a preferred embodiment of the present invention, a kind of composition for administering gaseous acrolein, by following percent by volume
Component is mixed and is made:
In a preferred embodiment of the present invention, a kind of composition for administering gaseous acrolein, by following percent by volume
Component is mixed and is made:
In a preferred embodiment of the present invention, it is a kind of administer gaseous acrolein composition in HNO3The amount of solution mass is dense
Degree is 0.1mol/L.
In a preferred embodiment of the present invention, it is a kind of administer gaseous acrolein composition in AgNO3The mass body of solution
Product percentage is 5%.
In a preferred embodiment of the present invention, it is a kind of administer gaseous acrolein composition in KMnO4The amount of solution mass
Concentration is 0.1mol/L.0.1mol/L KMnO4It prepares: weighing about 3.3g KMnO4Add 1000mL water boil 15min. jump a queue it is quiet
Day or more is set, melts funnel filtering with hanging down, it is spare.
In a preferred embodiment of the present invention, it is a kind of administer gaseous acrolein composition in AuNRs solution mass amount
Concentration is 5.0 × 10–4mol/L。5.0×10–4The preparation of mol/L gold nanorods (AuNRs) solution is using Chinese patent (application
Numbers 201410075687.5；Publication number CN103830868A) method carry out.
In a preferred embodiment of the present invention, the composition is loaded in purification device and uses, the purification device packet
The online clarifier for removing methacrylaldehyde in real time is included, composition is packed into purification device, by aspiration pump by room air by air inlet
Channel is pumped into composition, and air is escaped by outlet passageway after purification, and air inlet and outlet drive indoor air flows to form circulation,
The online methacrylaldehyde removed in room air in real time is realized by air circulation.Careat 40m2, spatial volume 120m3And it is empty
When acrolein concentrations are 10.4-11.1 times exceeded in gas, the dosage of the composition is 2L, and the processing time is 1h.
Mechanism of the invention is as follows:
At normal temperatures and pressures, when gaseous acrolein passes through water, part propylene aldehyde is dissolved oxygen and is oxidized to acrylic acid, anti-
Answer formula are as follows:
Most of methacrylaldehyde escapes from water and pollutes air.
When gaseous acrolein passes through composition solution, each component of methacrylaldehyde and composition reacts.Due to CH2
=CH2Aldehyde radical is unstable in-CHO, by KMnO4Oxidation generates CH2=CH2- COOH, to remove CH in room air3The dirt of CHO
Dye, reaction equation are as follows: 6CH2=CH-CHO+2KMnO4+4H+→6CH2=CH-COOH+2Mn2++2K++2H2O simultaneously, CH2=
CH2- CHO also can be by Ag+It is oxidized to CH2=CH2- COOH, reaction equation are as follows:
CH2=CH2-CHO+Ag+→CH2=CH2-COOH+Ag0
The Ag of generation0Au@Ag ↓ NRs, reaction equation are formed to be wrapped in the surface AuNRs are as follows:
AuNRs+Ag0→Au@Ag↓NRs
The Ag on the surface Au@Ag ↓ NRs0By KMnO4Oxidation generates Ag+, reaction equation are as follows:
KMnO4+5Ag0+8H+→5Ag++Mn2++K++4H2O
As a result Ag+It has been catalyzed KMnO4With CH2=CH2The progress of-CHO redox reaction, AuNRs is to Ag in overall process+
It is catalyzed KMnO4Aoxidize CH2=CH2- CHO reaction shows strong superposition, as shown in Fig. 1.
Fig. 2 a and 2b are please referred to, there is one layer of light on the surface that AuNRs can be observed, this is because Ag+By CH2=
CH2- CHO is reduced to Ag0, the latter is deposited on the surface of AuNRs, to form Au@Ag ↓ NRs.Mass spectral analysis shows109Ag/197The ratio of Au is 0.096 in pH=9.2.These fact confirmations CH2=CH2- CHO is in AuNRs-Ag+Au@is truly had in system
Ag ↓ NRs product generates.
