## Abstract A novel method based on thermal desorption was developed for the trapping of aromatic amines from azo dyes reduction in liquid phase. Combining GCโ€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 โชˆ70% with R
