电感偶合等离子体原子发射光谱法测定氯化聚乙烯中的钙含量

Inductively coupled plasma atomic emission spectrometry method for the determination of calcium in chlorinated polyethylene

建立了电感偶合等离子体原子发射光谱法分析氯化聚乙烯中钙含量的方法。采用标准曲线法分析氯化聚烯中钙含量,结果表明,钙在氯化聚乙烯样品中的平均加标回收率为98.62%,相对标准偏差小于1.29%,实验中钙的检出限(DL=3 Sb/m)为0.011μg/mL。

Set up feeling coupled plasma atomic emission spectrometry analysis of the chlorinated polyethylene calcium miscellaneous method. This experiment used standard curve method to analyze the calcium content of propylene chlorination polythelene, the results indicate that the calcium in the chlorinated polyethylene samples of the average labeled recovery is 98.62%, RSD less than 1.29%, the experiment of calcium in the detection limit （DL=3 Sb/m ）for 0.011 ug/mL
