| Abstract: | The analysis of diethylenetriamine (DETA) at trace levels in water by gas chro matography was presented. Using methylation agent, DETA was derivatized to the N.N.N' ,N' ,N"-pentamethyldiethylenetriamine (MDETA), then extracted by organic solvent and detected with FID. The detection limit was 1 ppm. The relative deviation was less than 10% with 1,6-hexdiamine as internal standard. |
