Abstract:
Objective To provide scientific basis for formulating National Standard Method for determination of 1,1_dichloroethene in water. Methods The method of head space gas chromatography was established in this assay. Results This method revealed good seperating efficiency and good linear relationship (r=0.9995,n=6). The detection limit was 0.2 ?g/L. The recovery rates of the blank drinking water samples to which was added standard solution containing 10, 20 and 40 ?g/L 1,1_dichloroethene respectively were 108%, 101% and 97% respectively, their related standard deviations were 4.6%, 4.2% and 2.8% respectively. Under the similar procedure as above, the recovery rates of the blank source water samples, added with standard solution containing 10, 20 and 40 ?g/L respectively, were 92%, 94% and 97%, their related standard deviations were 7.0%, 5.0% and 3.3% respectively. Conclusion This method was simple, convenient and effective. The levels of recovery rates and precision of this method all accorded with the requirements of the determination of 1,1_dichloroethene in water.
