P_(538)-硅球色谱分离、AAS法测定氯化稀土中的常见元素

Determination of Common Elements in Rare Earth Chloride by Means of P_(538)-Silicon Prill Chromatographic Fractionation and AAS

采用自制P_(538)-硅球色谱柱分离稀土、钍,空气—乙炔火焰原子吸收法(AAS法)测定常见元素K、Na、Mg、Zn、Ni,研究了分离条件等,该法可适用于氯化稀土中常见元素的分析。

Common elements,K, Na, Mg, Zn, Ni can be assayed by means of fractionating rare earth and thorium with self—made P_(538)-silicon prill chromatographic column and the air-acetylene flame atomic absorption spectroscopy(AAS). The fractionating conditions are studied. This method is applicable for analyzing common elements in rare earth chloride.
