摘要
Abstract
A method for the determination of acetaldehyde and acrolein in surface water by headspace gas chromatography was studied.As a result,the temperature of 80 ℃,the balance time of 20 min,the NaCl amount of 4 g and the water volume of 10 mL were chosen as the optimization of headspace conditions.The detection limits was 0.05 mg/L of acetaldehyde and 0.08 mg/L of acrolein.The results showed that the re-covery of acetaldehyde ranged between 84.8% - 109.1% and the recovery of acrolein ranged between 79.2% -108.3%.The relative standard deviations were ranged from 2.4% to 10.7%.关键词
