Description
Technical field
The invention belongs to Techniques for Indoor Air Purification field, be specifically related to a kind of ammonia and remove composition in real time online.
Background technology
Ammonia is a kind of colourless and have the gas of intense stimulus stink.Ammonia in current room air comes from the concrete admixture used in construction, the wood-based plate (glued board, core-board, medium density fibre board (MDF) and particieboard etc.) of interior decoration, furniture (Wood-based Panel Furniture, cloth art furnishings, kitchen furniture etc.), and other underproof all kinds of ornament materials (brightening agent, binder, white glue with vinyl, coating etc.).People can feel that the least concentration of ammonia is 5.3mg/m
3[2].China's " Indoor Air Quality standards " regulation formaldehyde standard value is 0.20mg/m
3, moisture during excessive concentration in Absorbable rod skin histology, makes histone sex change, and makes tissue fat saponification, destroys membrane structure, also causes cardiac arrest by the acting in opposition of trigeminal neuralgia tip and breathe to stop, and has a strong impact on human body physical and mental health.
For removing the ammonia of house decorative material release to the pollution of room air, domestic and international employing is ventilated, plantation flower plant is (as fragrant thoroughwort, evergreen, the ombrophytes etc. such as gold Pueraria lobota), indoor air purification equipment is (as active carbon, anion generator, ozone, photocatalysts etc. are independent or coordinate air-conditioning), absorbing liquid is (as 0.01N sulfuric acid, 5% boric acid, 5% phosphoric acid and malic acid etc.), solid absorbent is (as acid quartz sand, diatomite, oxalic acid, wolframic acid and the sensitive agent formed with the gas agent of alizarin network and polyethylene powder, by the glass fiber filter paper that 3% boric acid-20% glycerine mixed liquor or 8.6% oxalic acid-50% glycerine mixed liquor soak into, phosphoric acid-sweet oil impregnated non-woven fabrics etc.), air purifier, catalytic oxidation ammonia, corncob absorption method, intensified by ultrasonic wave air stripping deamination [10], and break point chlorination method, selective ion exchange method and bioanalysis etc.Said method has his own strong points, have in various degree except ammonia effect (clearance is about 10-50%), but still there is cleaning equipment costliness, break point chlorination method operating cost is high and cause secondary pollution, the ammonia nitrogen waste water of selective ion exchange method middle and high concentration needs process further, ammonia aeration method is not suitable for the use in winter in cold, and bioanalysis floor space is large, the limitation such as low temperature aging rate is low.
Summary of the invention
The object of the invention is to overcome prior art defect, provide a kind of ammonia to remove composition in real time online.
Concrete technical scheme of the present invention is as follows:
A kind of ammonia removes composition online in real time, is mixed and make by the component of following percent by volume:
Wherein, the concentration of the humic acid aqueous solution is 4.5 ~ 5.5g/L, FeSO
4the concentration of the aqueous solution is 1.0 ~ 2.0g/L, NaHCO
3the concentration of the aqueous solution is 0.8 ~ 1.2g/L, and the concentration of aqueous ascorbic acid is 0.8 ~ 1.2g/L.
Mechanism of the present invention is as follows:
Ammonia (NH in room air
3) absorbed by humic acid (HA) aqueous solution, under faintly acid (pH=5) condition, generate the ammonium humate (NH of difficult ionization
