This method is based on the national standard GBT 2912 1-2009, extracting formaldehyde in textiles with water, using acetylacetone as a color reagent, and measuring the absorption wavelength at 420 nm after incubation to determine the formaldehyde content in the solution. Users only need to put the formaldehyde extract into the Gallery automatic analyzer, and the instrument can automatically complete a series of steps such as adding acetylacetone, incubation, detection, concentration calculation, etc., without the need to be on duty. The method has fast detection speed, low reagent consumption, accurate results, and can greatly save labor. It is of great significance for the rapid and accurate quantitative detection of formaldehyde content in large-scale textiles.
