Conventional characterization of plutonium contaminated neoprene gauntlets and cellulosic materials are highly difficult not only due to the non‐geometric and unconventional nature of the sample, but also the radio‐toxicity associated with them. An analytical method based on direct current arc atomic emission spectrometric (D.C.Arc AES) technique was developed for direct determination of 22 metallic impurities in contaminated neoprene gauntlets and cellulose samples. The samples were incinerated to powder form and analyzed against seven point standardization using graphite standards. The interference free best performed emission lines of the analytes were chosen as the analytical lines for establishing the calibration curves required for their estimation. The linear dynamic range, sensitivity, detection limit, precession associated with these analytical lines were evaluated in the graphite matrix. Energy dispersive X‐ray fluorescence spectrometry has also been employed for comparative evaluation of the analytical performance of the developed AES based method as well as analysis of the actual samples. D.C.Arc AES based method was found to have 20% precession, while that for EDXRF was 10%. However, elements with lower Z values and lower concentration can only be determined by AES.

基于AES和XRF的氯丁橡胶手套和纤维素材料中痕量和微量金属成分的比较评估

p污染的氯丁橡胶手套和纤维素材料的常规表征非常困难，这不仅是由于样品的非几何和非常规性质，还在于与之相关的放射毒性。建立了一种基于直流电弧原子发射光谱法（DCArc AES）的分析方法，用于直接测定受污染的氯丁橡胶手套和纤维素样品中的22种金属杂质。将样品焚烧成粉末形式，并使用石墨标准品对七点标准进行分析。选择分析物的无干扰性能最佳的发射谱线作为分析谱线，以建立估算所需的校准曲线。线性动态范围，灵敏度，检测极限，在石墨基质中评估了与这些分析线相关的进动。能量色散X射线荧光光谱法也已用于比较评估已开发的基于AES的方法的分析性能以及对实际样品的分析。发现基于DCArc AES的方法进动为20％，而EDXRF为10％。但是，具有较低Z值和较低浓度的元素只能通过AES确定。
