连续流动注射法测定水中挥发酚的含量

摘要

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。%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 detec
