Abstract
The invention relates to a formaldehyde testing reagent which is prepared from a reactant and a color development reagent, wherein the reactant is prepared from the following components in parts by weight: 5-12 parts of Ba(OH)2, 0.5-5 parts of nano TiO2 photocatalyst, 1-4 parts of amino acid and 0.8-3 parts of tea polyphenol. The formaldehyde testing reagent has a scientific and reasonable design due to being matched with a vessel of the formaldehyde testing reagent, and can be used for catching and adsorbing formaldehyde and displaying the content of formaldehyde by color changes. When objects to be tested are absorbed into the vessel and an interlayer in the middle part of the vessel is taken out, the content condition of the formaldehyde in the objects to be tested can be tested through chemical reaction for 1-3 seconds. The invention has the advantages of convenience in carrying, simplicity in use, high speed, flexibility, visibility, microscale, accuracy and high repeatability.
Description
Technical field
The present invention relates to a kind of formaldehyde detectable and container thereof.
Technical field
Formaldehyde is a kind of colourless, and the gas of intense stimulus smell is arranged.Highly volatile during room temperature is along with the rising evaporation rate of temperature is accelerated.Formaldehyde is the material than high toxicity, preferentially controls on the list formaldehyde at China's toxic chemical and is in second.Formaldehyde is defined as carcinogenic and teratogenesis shape material by the World Health Organization (WHO), is the allergen of generally acknowledging, also is one of potential strong mutagen.Studies show that: formaldehyde has strong carcinogenic and short cancer effect.The lot of documents record, formaldehyde mainly shows aspects such as allotriosmia, stimulation, allergy, abnormal pulmonary function, dysfunction of liver and immunologic dysfunction to health effects.When its concentration reached 0.06-0.07mg/m3 in every cubic metres of air, slight asthma will take place in children.When formaldehyde in indoor air content is 0.1mg/m3, peculiar smell and sense of discomfort are just arranged; When reaching 0.5mg/m3, can stimulate eyes, cause and shed tears; Reach 0.6mg/m3, can cause throat discomfort or pain.When concentration is higher, the vomiting that can cause nausea, it is uncomfortable in chest to cough, asthma even pulmonary edema; When reaching 30mg/m3, meeting is the 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 the dna single chain commissure and DNA and protein commissure and suppress dna damage reparation, pregnancy syndrome, cause neonatal chromosome disorder, leukaemia, cause the decline of teenager's memory and intelligence.Formaldehyde is the major pollutants of finishing and furniture.Its release period reaches 3-15, and meeting heat chance tide will evaporate from the material deep layer, serious environment pollution, and therefore, we often need carry out the content of formaldehyde detection to environment on every side, are unfavorable for healthy environmental factor with elimination.
Summary of the invention
The technical problem to be solved in the present invention provides kind of easy formaldehyde detectable and container thereof, and this formaldehyde detectable matches with its container, and design science is reasonable, easy to carry, fast and flexible.
In order to solve the problem that prior art exists, the technical solution used in the present invention is:
The formaldehyde detectable is made up of reactant and developer two parts, and described reactant is made of according to the following number of weight ratio following component:
Ba (OH) 2: nano titanium oxide photocatalyst: amino acid: Tea Polyphenols=5-12: 0.5-5: 1-4: 0.8-3.
Described developer is made of according to the following number of weight ratio following component:
Phosphate buffer: citric acid=10-35: 1-12.
Described formaldehyde detectable is made up of reactant and developer two parts, and described reactant is made of according to the following number of weight ratio following component:
Ba (OH) 2: nano titanium oxide photocatalyst: amino acid: Tea Polyphenols=10: 3: 2: 1.
Described developer is made of according to the following number of weight ratio following component:
Phosphate buffer: citric acid=20: 9.
The container of formaldehyde detectable, described container are divided into two-layer up and down, and developer is equipped with in lower floor, and reactant is equipped with on the upper strata, and be middle with movable interlayer interval, is stamped container cover on the container head.
Advantage and effect that the present invention had are:
Match with its container design science, rationally of formaldehyde detectable of the present invention can seizure, absorbing formaldehyde and show content of formaldehyde by change color.After being inhaled in the container and taking out the interlayer at container middle part, examined object, can predict content of formaldehyde situation in the checking matter by chemical reaction 1-3 second.The present invention is easy to carry, use is simple, fast and flexible, has advantage directly perceived, quick, micro-, accurate, that reappearance is high.
