摘  要:[目的]建立流动注射分光光度法测定水中挥发酚的方法。[方法]采用全自动流动注射分析仪,对水样中的挥发酚进行方法学实验,选择出最佳的实验条件。[结果]在最佳条件下,方法在2.0~200.0μg/L的浓度范围内具有良好线性(r=0.9993),方法的检出限为0.9μg/L,相对标准偏差为1.42%,该方法用于水样检测,获得较为满意的结果,平均回收率为94.5%~112.4%,与国家标准方法比较,差异无统计学意义。[结论]该方法准确性高,重现性强,且自动化程度适用于大批量样品的测定。[Objective] To establish a method for determination of hydroxybenzene in drinking water by flow injection spectrophotometry. [Methods] Hydroxybenzene in drinking water was determined by flow injection spectrophotometry,and the best experimental conditions were chosen for that purpose. [Results] In the best conditions,the linear range was 2.0-200.0 μg/L,the detection limit of the method was 0.9 μg/L,RSD of the determination of standard solution was 1.42%.The method was applied for analysis of drinking water,with satisfactory results obtained,and the average recovery was 94.5%-112.4%.The samples were determined by the proposed method and standard method.The results obtained showed no significant difference from those achieved by the international method. [Conclusion] This method is accurate and reproducible,suitable for the determination of hydroxybenzene in drinking water.
