Quantitative Determination of Primary Aromatic Amines in Recycled Cold-Cure and Flexible Foams

A reliable method for the quantification of aryl amines in cold-cure and flexible foams from recycled mattresses is described in the following application. The focus was set on two substances, 2,4-diaminotoluene (TDA) and 4,4-diaminodiphenylmethane (DAPM), which are mandatory to be determined before processing the recycled foam due to their carcinogenic properties.
