摘要
报道了Ｐ５０７－ｐＭＢＰ溶剂浸渍滤纸（ＳＩＦＰ）的制备及其吸附性质；提出含微量Ｚｒ、Ｈｆ的岩矿样品经碱熔分解后用强阳离子交换树脂静态吸附分离大量干扰元素，再用Ｐ５０７－ＰＭＢＰＳＩＦＰ富集Ｚｒ与Ｈｆ，然后用ＸＲＦ光谱直接测定ＳＩＦＰ上Ｚｒ、Ｈｆ的方法；考察了阳离子交换树脂分离干扰元素的条件，以及在残留干扰元素存在下Ｐ５０７－ＰＭＢＰＳＩＦＰ对Ｚｒ、Ｈｆ的富集情况等；对分析误差的来源，样品分析的精密度，ＳＩＦＰ样片的稳定性等也进行了讨论；所拟方法经用ＧＳＲ及ＧＳＳ系列部分地质标准样品分析验证，其结果与推荐值符合。
he preparation methods and the adsorption properties of P507-PMBP solvent impregnatedfilter paper(P507-PMBP SIFP)are reported.The sample is decomposed by alkali fusion and theinterfering elements are statically separated with strong cation exchange resin. The Zr and Hf inthe solution are preconcentrated on a P507-PMBP SIFP disc as thin film specimen and determinedby XRF directly.The separation conditions and the effect of residual interferents on the adsorption of Zr and Hf on P507-PMBP SIFP are investigated. The method has been tested on referencesamples GSR-1,2,3,4,6 and GSS-5 and the results agree well with the recommended values.
