摘要
根据纺织品重金属检测的新标准GB/T17953.1—2006《纺织品重金属的测定第1部分:原子吸收分光光度法》操作规程,酸性汗液条件下萃取出游离重金属,在原子分光光度仪石墨炉上测定其含量,以铅、镉、铬为例,对整个测试过程中各不确定度的分量进行了评定、合成,最后给出了合成不确定度和扩展不确定度,以及不确定度的主要来源。
According to the operating process of new standard GB/T 17953. 1-2006 Textiles Determination of Heavy Metals- Part 1 ：Atomic absorption spectrophotometry, the heavy metals, such as Pb, Cd, Cr etc., were extracted in acid perspiration solution and detected by GTA. Uncertainty component was evaluated and composed. The composed and expanded uncertainties of three metals, as well as main source of uncertainties were obtained.
