## Abstract A novel method based on thermal desorption was developed for the trapping of aromatic amines from azo dyes reduction in liquid phase. Combining GC‐MS, the detection limits for 21 kinds of aromatic amines ranged from 0.1 to 3 mg/kg. The recoveries of most aromatic amines were ⪈70% with R
