原子吸收光谱法测定PVC中铁含量

Iron contents in PVC determination with atomic absorption spectrometry

采用阶段性程序升温法对PVC进行焙烧与硝酸酸化的前处理,运用原子吸收光谱仪对PVC中铁含量进行分析检测。结果表明,该方法简单、快速,重现性好,适用于聚氯乙烯行业对PVC中铁含量的测定。

Step temperature programming was used for calcinations of PVC and pretreatment of nitric acid acidification.Iron contents of PVC were analysed and determined by atomic absorption spectrograph.The atomic absorption spectrometry was simple,quick and better repeatability,and was applicable to iron contents determination.
