| Abstract: | 2-isopropyl-3-methoxypyrazine, 2-methylisobomeol and geosmin in textile were extracted by solvent hexane and dichloromethane, respectively, and determined by GC - MS. Effects of solvent, temperature and extracted time on the recovery of odor- ous substances were investigated. The results showed that the recovery of odorous substances extracted by solvent hexane was higher than by solvent dichloromethane, and more than 85% of odorous substances were recovered when extraction was carried out by solvent hexane at 60 -80℃ for 15 min and the RSD was less than 5% （n =5）. |
