Abstract
The invention discloses a kind of food formaldehyde quick detection reagent, its material for including following weight portion, specially：Sodium metaperiodate 3% 5%, potassium hydroxide 5% 10%, petroleum ether 2% 3%, sodium sulphate 4% 6%, citric acid 5% 6%, Sodium Benzoate 2% 3%, remaining be distilled water.By above-mentioned material proportion, food formaldehyde quick detection reagent of the invention can be detected effectively to the formaldehyde in food, and have the advantages that reaction speed is fast, sensitivity is high, good stability.
Description
Technical field
The present invention relates to formaldehyde examination technical field, more particularly to a kind of food formaldehyde quick detection reagent.
Background technology
At present, as the fast development of industrial technology, Sudden Pollution Accident are continuously increased, threaten human health
And ecological environment is destroyed, seriously govern the ecological balance and society, expanding economy.Abrupt polluting accident is taken precautions against urgently to solve
Problem certainly is a lot, and top priority is to set up monitoring method for emergency technology, once contamination accident occurs, can rapidly put into monitoring,
Accurate contamination data is provided within the most short time, to prevent the diffusion of pollution and taking counter-measure to provide scientific basis.
Therefore, extremely strong for time and spatial character, for the significant Sudden Pollution Accident of change at random, Site Detection is obtained
The a timely and accurate answer accurate perfect answer of test in laboratory that comes too late than one it is valuable
It is many.In-situ check and test method is typically to carry out real-time detection in workplace, i.e., measure in a short time in sample with the presence or absence for the treatment of
Survey material and its concentration.Method for Site Detection needs that sampling quantity is few, and possesses the degree of accuracy and spirit higher
The features such as sensitivity, instrument that is quick, using easy to operate are easy to carry.More ripe in-situ check and test method has test paper at present
Method, detection tube method, miniature LHD units, dirt thing experimental method, portable instrument method etc..
Formaldehyde is a kind of gas that is colourless, having intense irritation, and it has volatile characteristic.Formaldehyde is indoor environment
One of major pollutants, are defined as carcinogenic and teratogenesis material by the World Health Organization.World Health Organization（WHO）Regulation exposure
Safe concentration in formaldehyde in 30 minutes is 80ppb, Occupational Safety and Health Administration of the U.S.（OSHA）What regulation was allowed
Formaldehyde exposure concentration is 750ppb, and extreme danger concentration（Work DLH）It is 20ppm.The formaldehyde for sucking high concentration occurs
The serious stimulation of respiratory tract and oedema, eye shouting pain and headache.The formaldehyde of Long Term Contact low concentration can cause slow poisoning, cause head
Dizzy weak, neurasthenia, mental depression and chronic respiratory disease etc..Harm of the formaldehyde to infant and pregnant woman is more serious,
The serious consequences such as fetal anomaly and miscarriage can be caused.
