Abstract:
The continuous flow analysis（without using organic solvents） has been used for determining the volatile phenol in water. 30 samples can be analyzed per hour. The RSD=1.36% for 1.0 × 10-8 samples， and RSD=5.03% for 2.0 ×10 -9 samples. Since the online distillation is used， the samples do not need to be pretreated. It can completely replace the manual methods which determine the volatile phenol in water.

摘要：
采用连续流动分析法(不使用有机溶剂)测定水中挥发性酚,每小时可以分析30个样品,质量分数1.0×10-8的样品RSD=1.36%,质量分数2.0×10-9的样品RSD=5.03%,因为采用了在线蒸馏,所以样品不需要前处理,能够代替手工方法对水中挥发性酚进行测定。
