- Abstract
- A novel flow-injection chemiluminescence (CL) method for the determination of triethylamine had been established in this study. Based on the chemiluminescence reaction between triethylamine and sodium hypochlorite in alkali condition, the fluorescein has strong sensitization in this chemiluminescence reaction. Under the optimized conditions of chemiluminescence reaction, FI parameters and the absorbing efficiency of triethylamine in the air, the enhanced intensity of chemiluminescence was proportional to the concentration of triethylamine in the range of 0.001~0.10g/L, and the relative standard deviation was 0.89% (n=11) at 0.05g/L triethylamine. The detection limit was 0.8mg/L in aqueous. The proposed method had been applied successfully to determine triethylamine in the lab air.
