Abstract

The application is related to technical field of environmental pollution treatment, and in particular to the compound urea peroxide reagent and preparation method and application of a kind of improvement interior free formaldehyde.The reagent is made up of following raw material：Hydrogen peroxide, urea peroxide and sodium acid carbonate.By the present invention in that being compounded with low concentration hydrogen peroxide, urea peroxide and sodium acid carbonate, it is good for the free formaldehyde treatment cost obvious regulation effect of low, selective good, removal effect, have no toxic side effect, non-secondary pollution, there is indoor sterilization bacteriostasis simultaneously, and can be used for disposing the secondary pollution problem of bioanalysis, free formaldehyde clearance reaches more than 85%.

Description

Administer the compound urea peroxide reagent and preparation method and application of indoor free formaldehyde
Technical field
The application is related to technical field of environmental pollution treatment, and in particular to a kind of compound peroxide of improvement interior free formaldehyde Change urea reagent and preparation method and application.
Background technology
Formaldehyde is a kind of gas that is colourless, having intense stimulus type smell, and Long Term Contact low dosage formaldehyde can cause chronic exhaling Tract disease, feminine menstrual disorder, pregnancy syndrome are inhaled, causes the reduction of neonate's constitution, chromosome abnormality, or even cause nasopharynx Cancer.High-concentration formaldehyde is all toxic to nervous system, immune system, liver etc..Formaldehyde also has teratogenesis, carcinogenesis, connects for a long time The people of formaldehyde is touched, nasal cavity, oral cavity, nasopharynx, throat, skin and gastral cancer may be caused.
Current elimination method of formaldehyde mainly includes：
Physical adsorption techniques (the big poor selectivity of consumption)：The strong adsorptivity of the various main applied activated carbons of air purifier is inhaled The pollutants such as attached formaldehyde.
Photocatalyst method (effect is good but big using limitation)：Under the irradiation of light, similar photosynthetic light can be produced to urge Change reaction, produce oxidability extremely strong free hydroxy and active oxygen, it is oxidable with very strong photoredox function Decompose various organic compounds and part inorganic matter.
Bioanalysis (action time is short, there is secondary pollution risk)：Cleaning organic waste gas are that microorganism is given birth to organic matter as it Carbon source and the energy long and the method that is oxidized, is degraded to nontoxic, harmless inorganic matter.
The content of the invention
It is to be administered for indoor free formaldehyde, the present invention provides a kind of compound peroxidating for administering indoor free formaldehyde Urea reagent and preparation method and application.
The technical scheme is that：
A kind of compound urea peroxide reagent for administering indoor free formaldehyde, is made up of following raw material：Hydrogen peroxide, peroxidating Urea and sodium acid carbonate.
The mass concentration of the hydrogen peroxide is 30% aqueous solution.
The proportioning of aqueous hydrogen peroxide solution, urea peroxide and sodium acid carbonate is 100mL:50g:10g.
A kind of preparation method of compound urea peroxide reagent for administering indoor free formaldehyde, comprises the following steps：It is accurate Really measure in hydrogen peroxide to distilled water, add sodium acid carbonate, urea peroxide is added after dissolving.
Hydrogen peroxide is configured to the aqueous solution that mass concentration is 3%.
Application of the compound urea peroxide reagent in indoor free formaldehyde is administered.
Reaction mechanism：CH4N2O·H2O2===H2NCONH2+H2O2
HCHO+H2O2===HCOOH+H2O
HCHO+H2NCONH2===H2NCONHCH2OH
HCOOH+NaHCO3===HCOONa+H2O+CO2↑
Compared with prior art, the present invention has following excellent technique effect：
By using low concentration hydrogen peroxide, urea peroxide and sodium acid carbonate compound, for free formaldehyde treatment cost it is low, The selectivity obvious regulation effect of good, removal effect is good, has no toxic side effect, non-secondary pollution, while having the antibacterial work of indoor sterilization With, it is possible to the secondary pollution problem for disposing bioanalysis, free formaldehyde clearance reaches more than 85%.
Specific embodiment
The present invention is illustrated with reference to embodiments, but does not limit the invention to these specific embodiments.
Embodiment 1
Except formaldehyde formula of liquid：The accurate 100mL concentration that measures is for 30%H2O2Into 1L distilled water, 10g NaHCO are added3, it is molten 50g urea peroxides are added after solution.5 hours now with the current shelf-lifves of the solution.Scene is administered needs atomized spray.First in confined chamber Aldehyde regulation effect test data is as shown in table 1：
The closed indoor formaldehyde regulation effect test data of table 1
