地表水中锑快速检测技术的应用

摘要

The results showed the linearity relationship were excellent,the detection limit was 0.50μg/L,the accuracy and precision was good,the recoveries obtained by standard addition ranged from 86.0% to 120%.The influence of the interfering elements was analyzed,and the interference of 20 times copper was eliminated.Compared with inductively coupled plasma mass spectrometry,the results of statistics t test showed no significant difference between them.This technology is simple,fast,cheap,reliable,can be used in the laboratory or in the scene.%对一种地表水中锑的快速检测技术进行实际应用.结果表明,该技术的线性关系良好,检出限为0.50μg/L,准确度和精密度良好,加标回收率为86.0%~120%.对干扰元素的影响进行分析,消除了20倍铜的干扰.与电感耦合等离子体质谱法的进行比对,结果没有显著性差异.该技术的操作简便、成本较低、结果可靠,既可在实验室内快速分析检测,也可在地表水污染事故现场进行快速检测.
