How to detect excessive formaldehyde in furniture has always been a hot topic. We should pay attention to the environmental protection of the house while decorating the house. How to detect excessive formaldehyde in furniture is called a top priority. Jiuzheng Building Materials Network has summarized some small strategies for everyone, I hope I can help you!
The excessive formaldehyde in furniture is now widely recognized as the first killer in the world. The release period of toxic gases in the air is long, and it is difficult for residents to notice when it is slightly exceeded. When the standard exceeds four or five times, the occupant can smell the smell. Finding a formal testing agency to do formaldehyde testing has become an indispensable procedure for staying in a new home. How does CH2O detect formaldehyde?
Step / method
Furniture formaldehyde exceeds the standard 1, formaldehyde detection box: easy and fast to operate; low sensitivity detection limit; can be operated on site and so on.
Furnace formaldehyde exceeding standard 2, electrochemical analysis method is based on the change of current (voltammetry), electric quantity (coulomb method) and potential (potential method) generated in chemical reaction, and the method of quantitatively analyzing the concentration of analyte in the reaction system There are two kinds of polarographic and potentiometric methods for formaldehyde detection.
Furniture formaldehyde exceeds standard 3. Spectrophotometry is a qualitative and quantitative analysis method based on the selective absorption of electromagnetic radiation by different molecular structures. It is the most common method for formaldehyde detection in living rooms, textiles and food.
The formaldehyde in the furniture exceeds the standard 4. The chromatographic method has strong separation efficiency, is not easily interfered by the color of the sample matrix and reagents, and is sensitive and accurate for the detection of complex samples. It can be directly used for the analysis and detection of formaldehyde in the living room, textiles and food.
Furniture formaldehyde exceeds the standard 5, the sensor for detecting formaldehyde - sensors for detecting formaldehyde include electrochemical sensors, optical sensors and photobiochemical sensors
Furniture formaldehyde exceeds standard 6, plant removal method: spider plant, tiger tail orchid, ivy and so on.
Jiuzheng Building Materials Network summary: how to detect furniture formaldehyde exceeds the standard, the house is best vacant for a period of time after renovation, if you are not at ease you can check whether the furniture formaldehyde exceeds the standard.
