摘要
文章采用原子荧光分光光度法测定纺织品中重金属元素砷的含量,研究与分析方法的线性范围、检出限、定量限、正确度和精密度,进行了不确定度的评定.实验结果表明,该方法的检出限为0.007 mg/kg,定量限为0.017 mg/kg,精密度＜10％,相对标准不确定度为2.4％,实验室能够满足标准方法的检测要求.
Abstract
The content of arsenic in textiles was determined by atomic fluorescence spectroscopy.The linear range,detection limit,quantitation limit,accuracy and precision of the method were stud-ied and analyzed,and the uncertainty was evaluated.The results show that the detection limit of this method was 0.007 mg/kg,the quantitative limit was 0.017 mg/kg,the precision was less than 10％,and the relative standard uncertainty was 2.4％.The laboratory can meet the detection requirements of the standard method.
