Description
Technical field
The present invention relates to technical field of chemistry, specially a kind of high-efficiency environment friendly composite Nano photocatalyst formaldehyde scavenger and its
Preparation method.
Background technique
Formaldehyde, chemical formula HCHO or CH2O, formula weight 30.03, also known as formaldehyde.Colourless gas has special penetrating odor, right
The irritating effect such as human eye, nose.Formaldehyde can be absorbed through respiratory tract, by cause tissue active oxygen increase, peroxidatic reaction of lipid,
Immune system and the large biological molecule effect etc. for influencing body damage body.Formaldehyde there is stimulation to make skin and mucosa
With, to human body have sensitization, allergic dermatitis, color spot, bronchial asthma etc. can be caused.It also has strong carcinogenicity
With rush canceration, such as nasopharyngeal carcinoma and leukaemia can be caused, be determined as carcinogenic by the World Health Organization and cause deformed material.
