Studying Rapid Determination of Formaldehyde in Textiles
Abstract: The method of rapid determination of formaldehyde in textiles is studied. Toxicity of formaldehyde is higher, has strong carcinogenic and promote cancer role. In textile auxiliaries industry, formaldehyde is widely used as a reactant. Two kinds of spectrophotometric method - AHMT spectrophotometric method and MBTH spectrophotometric method for determination of formaldehyde in textiles are studied, by measuring absorbance to determine the formaldehyde in textiles and whether conform to the requirements of the standard limit. The results have proved that these methods are rapid，simple，and reliable for the site determination；and preliminary screening of large amount of samples has no need of expensive instruments. In the case that a sample exhibits positive, it can be sent to the lab for quantitive determination.
