标准摘要
[中文适用范围]: 本标准规定了用原子吸收光谱法(AAS)测定钠(Na)来测定空气粉尘中聚丙烯酸酯(PA)高吸水性粉末的方法。 PA 粉尘样本收集在带有聚四氟乙烯过滤器和多孔塑料背垫的聚苯乙烯丙烯腈空气监测盒中。 该方法适用于测定收集到的超吸收性粉末,其含量范围为 0.2 μg 至 60 μg(检测限接近 0.2 μg)。 注:该测试旨在确定低含量的钠,并要求遵守非常清洁的处理条件。 使用钠含量极低的去离子/蒸馏水对于成功分析至关重要。 [外文原描述]: ISO 17191:2004 specifies a method for the determination of polyacrylate (PA) superabsorbent powders in airborne dust by measurement of sodium (Na) by atomic absorption spectrometry (AAS). PA dust samples are collected in polystyrene acrylonitrile air-monitoring cassettes with polytetrafluoroethylene filters and porous plastic backing pads. This method is applicable to the determination of collected superabsorbent powder in the range between 0,2 micrograms and 60 micrograms (limit of detection near 0,2 micrograms) of superabsorbent powders.
