Workplace air — Determination of particulate cadmium and cadmium compounds — Flame and electrothermal atomic absorption spectrometric method 工作场所空气.颗粒镉和镉化合物的测定.火焰和电热原子吸收光谱测定法
发布日期: 2023-05-30
本文件规定了使用火焰或电热原子吸收光谱法测定工作场所空气中颗粒镉和镉化合物质量浓度的方法。 10.2.2中规定的样品消解程序是否经过验证?用于选择镉化合物和含镉的颜料和玻璃搪瓷。 该分析方法已被验证用于测定10?ng到600?使用电热原子吸收光谱法测定每个样品的镉含量为0.15?微克到96?使用火焰原子吸收光谱法测定每个样品的镉μ g。?该程序适用的空气中镉的浓度范围部分由用户选择的采样程序确定。 该方法适用于ISO 7708中定义的空气颗粒的可吸入或可呼吸部分的个人采样,以及固定采样。

This document specifies a method for the determination of the mass concentration of particulate cadmium and cadmium compounds in workplace air, using either flame or electrothermal atomic absorption spectrometry.

The sample digestion procedure specified in 10.2.2 has been validated?for a selection of cadmium compounds and pigments and glass enamels containing cadmium.

The analytical method has been validated for the determination of masses of 10?ng to 600?ng of cadmium per sample using electrothermal atomic absorption spectrometry, and 0,15?μg to 96?μg of cadmium per sample using flame atomic absorption spectrometry.?The concentration range for cadmium in air for which this procedure is applicable is determined in part by the sampling procedure selected by the user.

The method is applicable to personal sampling of the inhalable or respirable fraction of airborne particles, as defined in ISO 7708, and to stationary sampling.
