| Abstract: | The application of determining the chloral in water using the method of capillary column cross - linked to DB - 624 separation and micro-capture deteetor-Headspaee 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 0.2 ug/L, SD is 0. 028 ug/L, RSD is 6.0% and the recovery of standard addition is between 88.7% -109%. |
