| Abstract: | Objective:To investigate the convenient and effective method for collecting the exhaled air and detecting trichloroethylene(TCE) in gas samples.Method:The exhaled air samples from workers were collected in 2L breathing-bag.The gases in workshops were collected by air-sample-collector.After concentrated with the activated carbon tube and detached by carbon bisulfate,the released liquid was determined by gas chromatography.Results:The correlation coefficient of working curve is r=0.998,while CV=3.25% and the recovery rate is 100.15%.The permeathed capacity for TCE in 100mg activate carbon is 3.0mg and the lowest detection limit is 4.0ng.Conclusion:The experiment showed that this method can meet the need for hygiene determination of TCE in gas samples. |
