建立连续流动注射分析法测定水中挥发酚的方法，选用自动进样器和在线蒸馏系统，标准和样品均在线蒸馏。试验结果表明：在2．0-200．0μg／L浓度范围内，体系吸光度值与挥发酚浓度呈良好的线性关系（相关系数〉0．999），检出限1．0μg/L，实际样品加标回收率在91．6％～110．3％，与国家标准方法比较，无明显差异，可用于水中挥发酚的定量检测。
建立連續流動註射分析法測定水中揮髮酚的方法，選用自動進樣器和在線蒸餾繫統，標準和樣品均在線蒸餾。試驗結果錶明：在2．0-200．0μg／L濃度範圍內，體繫吸光度值與揮髮酚濃度呈良好的線性關繫（相關繫數〉0．999），檢齣限1．0μg/L，實際樣品加標迴收率在91．6％～110．3％，與國傢標準方法比較，無明顯差異，可用于水中揮髮酚的定量檢測。

Using flow injection analysis and in - line distillation to determine volatile phenol in water was studied. Linear curve was obtained in the range of 2.0 - 200.0μg/L with a good linearity, the correlation coefficient was above 0.999 and the limit of detection was 1.0 μg/L. The average recovery range of volatile phenol in environmental water was 91.6% -110.3%. The results showed no significant difference from those achieved by the intermational method. The method was rapid, precise, convenient and was applied to the determination of volatile phenol in water with good results.
