摘要
采用微库仑法研究了环境水体中可吸附有机卤化物的测定方法。实验结果表明,该方法的最低检测浓度可达0.002mgCl·L-1,添加标准样品的平均回收率为97.9%—103.8%,变异系数为1.38%—3.19%,依样品不同所需分析运行时间在5—20min之间。该方法具有简便、快速、精密度和准确性高的优点,适用于环境水体中有机卤化物的分析。
It has been recognized that absorbable organic halogenides ( AOX) is a complex index capable of evaluating the quality of environmental water bodies,and indicate pollution levels in environmental water bodies. Our experimental results showed that the lowest detected concentration by this method could reach to 0.002 mg Cl·L-1, with averaged recoveries by sample spiked of 97.9%-103.8%, and variation coefficient of 1.38%- 3.19%, and the run time wasbetween 5 -20 min , respectively, for different sample analysis. This method is characterized by simplicity, speediness, good accuracy and precision, and is suitable for analysis of organic halogens in environmental water bodies.
