Abstract
锛?/p>
An analytical method for determination of trichloromethane and carbon tetrachloride
in drinking water by headspace gas chromatography has been established. The experimental
conditions were optimized. The minimum concentration of headspace sampling was 0.1 ug/L
锛?/p>
0.01
ug/L
锛?/p>
and the recovery rate ranged from 89 to 105% and 90 to 109%. The method is accurate
锛?/p>
rapid
锛?/p>
convenient
锛?/p>
low detection limit
锛?/p>
high sensitivity
锛?/p>
repeatability and stable recovery rate.
