摘要: 本文选择6种水中挥发性氯代烃作为研究对象,提出了两次相平衡/液上气相色谱法测定水中挥发性有机物的方法.系统推导了气液等体积和非等体积平衡,只分析气相就可测定水相浓度的理论关系式,研制了可变相平衡器.实测水中6种挥发性氯代烃的回收率在75—112%之间,相对标准偏差和相对误差小于13%.检出限范围在0.002—7μg·1-1.

Abstract: The twice phase equilibration is exemplified by the analysis of volatile organohalides in water.The method is based on the demonstration that the analysis of only gas phase equilibriums gives the concentration of volatile organohalides in water and their Henry's coefficients.The relative standard deviation and relative error is less than 13% for six volatile organohalides in water.The recover ranges is 75-112% and limit of detection is rang of 0.002-7μg·l-1.
