A New Method for Rapid Detection of Formaldehyde in Textiles

摘要

a new method for rapid detection of formaldehyde has been developed in this research. Under this method, the formaldehyde solution has condensation reaction with 4-amino-3-hydrazine-5 -mercapto-1,2,4-triazole (AHMT) and is oxidized by potassium periodate to produce purple chemical compounds. The method for rapid detection of the formaldehyde content in textiles has been optimized after researching primary influencing factors and considering the specimen extraction effect in GB/T 2912.1-2009.This method is sensitive, accurate and fast, taking only 12.5min, 9.6 times faster than the method provided in GB/T 2912.1-2009.
