| 摘 要： | 采用0．45μm玻璃纤维滤膜将工业废水分离为悬浮态和溶解态有机物质，以二氯甲烷为萃取剂，采用液液萃取一气质联用法对工业废水中溶解态有机物进行测定。优化的最佳萃取条件为：每个pH范围各萃取2次，静置时间5min，氯化钠加入量15g。方法的加标回收率为91．1％～103％，测定结果的相对标准偏差小于5％fH=6）。该法分析时间短，易于操作。

| Abstract: | Industrial wastewater was separated as suspended and dissolved organic matter by 0.45 μm glass fiber filter.The dissolved organic matter was determined by liquid-liquid extraction and GC-MS with extraction solvent CH2C12. Extraction condictions optimized were two times extraction of each pH range, holding time 5 min, and the amount of sodium chloride added 15 g. The spiked recoveries were in the range of 91.1%-103%. The relative standard deviation of determination results was less than 5%（n=6）. The method costs short analysis time and is easy to operate. |
