原子荧光光谱法测定水中低含量锡

To Detect Low Concentration Tin in Water by Atomic Fluorescnce Spectrometry

采用原子荧光光谱法测定水中锡,结果表明,方法检测限为0.14μg/L,在0.0μg/L^100μg/L范围内线性良好。不同浓度标准溶液测定的相对误差≤2.0%,实际样品测定的加标回收率在90.0%~109%之间,相对标准差≤6.1%,准确度和精密度均较好。

To detect low concentration Tin in water by atomic fluorescnce spectrometry. Detection limit 0.14 μg/L, within 0.0 μg/L - 100 μg/L its linear was good. Relative error for different concentration standard solution was less 2.0% , sample recovery rate was between 90.0% - 109%. Relative standard deviation was less 6.1%.
