Abstract
The invention provides a formaldehyde detection reagent. The formaldehyde detection reagent comprises the following components in parts by weight: 60-70 parts of soybean oil, 6-10 parts of cellulose, 2-3 parts of petroleum ether, 2-3 parts of sodium benzoate, 2-3 parts of etidronic acid and 1-2 parts of citric acid. The formaldehyde detection reagent is high in sensitivity; a minimum detection concentration is 0.1mg/m<3>; the formaldehyde detection reagent is well applied to detection of formaldehyde.
Description
Technical field
The present invention relates to a kind of formaldehyde testing reagent.
Background technology
Formaldehyde is a kind of colourless, has the gas of intense stimulus smell.Highly volatile during room temperature, along with the rising evaporation rate of temperature is accelerated.Formaldehyde is more highly toxic material, preferentially controls formaldehyde on list be in second at China's toxic chemical.Formaldehyde is defined as carcinogenic and causes deformed material by the World Health Organization (WHO), is generally acknowledged allergen, is also one of potential strong mutagen.Research shows: formaldehyde has strong carcinogenic and tumor promotion.Lot of documents is recorded, and formaldehyde is mainly manifested in the aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction on the impact of health.Its concentration reaches 0.06-0.07mg/m
3time, will there is slight asthma in children; When formaldehyde content in indoor air is 0.1mg/m
3time, just there are peculiar smell and sense of discomfort; Reach 0.5mg/m
3time, can stimulate eyes, cause and shed tears; Reach 0.6mg/m
3, can cause throat discomfort or pain.When concentration is higher, the vomiting that can cause nausea, coughs uncomfortable in chest, the even pulmonary edema of panting; Reach 30mg/m
3time, causing death immediately.Long Term Contact low dosage formaldehyde can cause chronic respiratory disease, cause nasopharyngeal carcinoma, colon cancer, brain tumor, paramenia, nuclear gene mutation, in DNA single chain commissure and DNA and protein commissure and suppress DNA damage reparation, pregnancy syndrome, cause neonatal chromosome disorder, leukaemia, cause teenager's memory and intelligence decline.Formaldehyde is the major pollutants of finishing and furniture.Its release period reaches 3-15, and heat and wet will evaporate from material deep layer, serious environment pollution, and therefore, we often need to carry out content of formaldehyde detection to environment around, to eliminate, are unfavorable for healthy environmental factor.
Summary of the invention
The invention provides a kind of formaldehyde testing reagent, PARA FORMALDEHYDE PRILLS(91,95) detects qualitatively very easily.
The invention provides a kind of formaldehyde testing reagent, comprise each component of following mass fraction: soybean oil 60-70 part, cellulase 6-10 part, sherwood oil 2-3 part, Sodium Benzoate 2-3 part, HEDP 2-3 part, citric acid 1-2 part.
Preferably, comprise each component of following mass fraction: 65 parts of soybean oils, 8 parts of cellulases, 2.5 parts of sherwood oils, 2.5 parts of Sodium Benzoates, 2.5 parts of HEDPs, 1.5 parts of citric acids.
The present invention also provides the application of above-mentioned formaldehyde testing reagent in formaldehyde examination.
Preferably, described application is to draw gas to be measured to pass into formaldehyde testing reagent, is heated to 55-60 ℃, and standing 30-35 minute, observes change color.Color changes proves that in gas to be measured, concentration of formaldehyde is greater than 0.1mg/m
3.
Formaldehyde testing reagent of the present invention is highly sensitive, and minimal detectable concentration is 0.1mg/m
3, can well be applied to the detection of formaldehyde.
