| Abstract: | A method for determining 27 poison compounds in bottled drinking water has been built utilizing solid-phase membrane extraction and GC-MS technique.The residues of compounds in drinking water were enriched by C18 solid-phase membrane and eluted by acetone.After concentrated,the acetone solution was determined by GC/MS.The results showed that recoveries of all analytes ranged between 60% and 120% with relative standard deviations less than 25%(n=8). |
