标准摘要
[中文适用范围]： 本标准规定了采用电感耦合等离子体发射光谱法（ICP-OES）测定聚乙烯（PE）和聚丙烯（PP）中金属含量的方法。 本标准适用于镁（Mg）、铝（Al）、钙（Ca）、锌（Zn）、铬（Cr）、钛（Ti）、铁（Fe）、锑（Sb）含量的测定、铜（Cu）、铅（Pb）、镉（Cd）等。 由于汞（Hg）具有挥发性，本文件不适用于测定。 该方法适用于PE、PP、PE/PP共聚物及其共混物的基础聚合物。 [外文原描述]： This document specifies a method for the determination of metal content in polyethylene (PE) and polypropylene (PP) by inductively coupled plasma optical emission spectrometry (ICP-OES). This document is applicable to the determination of the content of magnesium (Mg), aluminium (Al), calcium (Ca), zinc (Zn), chromium (Cr), titanium (Ti), iron (Fe), antimony (Sb), copper (Cu), lead (Pb), cadmium (Cd), etc. This document is not applicable to the determination of mercury (Hg) due to its volatility. This method is suitable for base polymers of PE, PP, PE/PP copolymer and their blends.
