| Abstract: |
| The application of determining the chloral in water using the method of capillary column cross-linked to DB-624 separation and micro-capture detector - Headspace Gas Chromatography is studied, compared with previous methods, which is accurate, reliable, labor-saving, time-saving, reagents-saving, and in line with the requirement of "green chemistry". MDL is 0.2ug/L, SD is 0.028ug/L, RSD is 6.0％and the recovery of standard addition is between 88.7%~109 %. |
