Abstract
The present invention relates to a kind of formaldehyde testing reagent, include the raw material of following parts by weight：79 parts of Phen, 57 parts of sodium benzoate, 46 parts of soybean oil, 68 parts of petroleum ether, 79 parts of citric acid, 35 parts of phenol reagent, 10 12 parts of acetylacetone,2,4-pentanedione, 13 parts of 1-hydroxy ethylidene-1,1-diphosphonic acid, 24 parts of sodium metaperiodate, 25 parts of phosphoric acid, 13 parts of butanedioic acid, 35 parts of glycerine, 01 parts of 2 amino, 3 amylene, 2 ketone, 40 60 parts of distilled water.Not only application method is easy for the formaldehyde testing reagent of the present invention, easy to operate, simple and easy, is suitable for the detection of generally formaldehyde in indoor air, and high sensitivity, detection speed are fast, are adapted to industrialized production.
Description
Technical field
The invention belongs to detection technique field, more particularly to a kind of formaldehyde testing reagent and its application.
Background technology
Formaldehyde is a kind of colourless gas, there is special penetrating odor, has stimulation to human eye and nose.A small amount of formaldehyde
It is not easy to be therefore easily perceived by humans, but has to human body and greatly endanger, effect can be irritating to the skin, formaldehyde main harm is shown as
To mucocutaneous stimulation, formaldehyde is magma noxious material, can be combined with protein, high concentration suction when respiratory tract occur tight
The stimulation and oedema, Eye irritation, headache of weight.There is sensitization harm to human body, direct skin contact formaldehyde may cause anaphylaxis skin
Inflammation, color spot, cutaneous necrosis.The harm of formaldehyde can also cause people's headache, weak, Nausea and vomiting, uncomfortable in chest, palpitaition etc..
Formaldehyde examination refers to, by specific method or instrument, contain empty gas and water, food, clothing, sheet material, leather etc.
Formaldehyde do quantitative detection.In view of threat of the formaldehyde for people's health, in the formaldehyde examination at home and in office space
Just become most important.At present, there is the problem of low sensitivity, complex operation, slow detection speed in in-situ check and test method, therefore need
Further to research and develop the detection reagent of excellent performance.
The content of the invention
It is an object of the invention to：A kind of formaldehyde testing reagent and its application are provided.
To achieve these goals, the present invention provides following technical scheme：
A kind of formaldehyde testing reagent, include the raw material of following parts by weight：
Phen 7-9 parts, sodium benzoate 5-7 parts, soybean oil 4-6 parts, petroleum ether 6-8 parts, citric acid 7-9 parts, phenol examination
Agent 3-5 parts, acetylacetone,2,4-pentanedione 10-12 parts, 1-hydroxy ethylidene-1,1-diphosphonic acid 1-3 parts, sodium metaperiodate 2-4 parts, phosphoric acid 2-5 parts, butanedioic acid 1-3
Part, glycerine 3-5 parts, 2- amino -3- amylene -2- ketone 0-1 parts, distilled water 40-60 parts.
Preferably, a kind of formaldehyde testing reagent, the raw material of following parts by weight is included：
8 parts of Phen, 6 parts of sodium benzoate, 5 parts of soybean oil, 7 parts of petroleum ether, 8 parts of citric acid, 4 parts of phenol reagent, acetyl
11 parts of acetone, 2 parts of 1-hydroxy ethylidene-1,1-diphosphonic acid, 3 parts of sodium metaperiodate, 3 parts of phosphoric acid, 2 parts of butanedioic acid, 4 parts of glycerine, 2- amino -3-
0.5 part of amylene -2- ketone, 50 parts of distilled water.
The detailed process of detection is as follows：Under test gas is collected, under test gas is passed through in formaldehyde testing reagent, is heated to
42-52 DEG C, 8-12 minutes are stood, observe color change, concentration of formaldehyde is higher than under test gas if being proved if color changes
