摘要
本文采用石墨炉原子吸收分光光度法对土壤中的铅进行测定.对元素的测定过程与测定结果进行阐述,最后进行汇总讨论与分析.结果表明,铅的检出限、精密度、准确度以及回收率均符合相关要求,满足《土壤质量 铅、镉的测定 石墨炉原子吸收分光光度法》(GB/T 17141-1997)[1]的标准.
Abstract
This paper uses graphite furnace atomic absorption spectrophotometry to determine the elements of lead in the soil.The measurement process and measurement results of lead is respectively elaborated,and finally a summary discussion and analysis are carried out.The results show that the detection limit,precision,accuracy and recovery rate of the lead meet the relevant requirements,and meet the requirements of"Soil quality--Determination of lead,cadmium--Graphite furnace atomic absorption spectrophotometry"(GB/T 17141-1997)[1].
