摘要
在顶空技术的基础上,建立了操作方便、快速、准确的自动顶空技术来测定饮用水中的三卤甲烷类消毒副产物,采用毛细管气相色谱和电子捕获检测器及自动顶空联用,具有检测的灵敏度高、重复性好、回收率高等优点。三卤甲烷的回收率在88.9%～97.5%之间,线性相关系数在0.997～0.999之间。三氯甲烷、一溴二氯甲烷、二溴一氯甲烷及三溴甲烷的检出限分别为0.096μg/L,0.089μg/L,0.098μg/L,0.251μg/L。
A simple, fast, precise method namely auto-headspace gas chromatograph composed of auto-headspace sampler and capillary chromatography with electron capture detector has been established to determine the disinfection by-products of trihalomethanes in drinking water. It is very sensitive with better repetition and high recovery. For trihalomethanes recovery ratio between 88. 9-97. 5% and correlation coefficients between 0. 997 to 0. 999 were obtained. The detection limits for trichloromethane, bromodichloromethane, dibromochloromethane and tribromomethane were 0. 096μg/L, 0. 089μg/L, 0. 098μg/L and 0. 251μg/L respectively.
