固相吸附-液相色谱-质谱法测定饮用水中痕量有机污染物

Analyses of Organic Pollutants in Drinking Water by SPE-LC-MS

通过对自来水中有机污染物的检测,初步了解和评价了某市自来水中有机物污染状况。采用XAD-2树脂对水中有机物进行富集、液相色谱-质谱联用(LC-MS)法测定部分有机污染物。结果表明,自来水厂出厂水中检出有机污染物含量均未超过国家饮用水水质标准,但UPVC型水管中水头水有机物含量略微高于铸铁型水管,中断水中有机物含量基本相同。

To analyse organic pollutants in Tap water, the current levels of organic pollutants in tap water in one city was evaluated. As XAD-2 resin for enrichment of organic in water, then liquid chromatography-mass spectrometry （LC-MS） detemine organic pollutants. The results showed that the city water detection of organic pollutants in water content did not exceed state drinking water standards, but type UPVC water pipes head slightly higher than the organic content-type castiron pipes, top water and organic content is basically the same.
