阳离子交换树脂填充纸吸附、X—射线荧光光谱法测定矿石及选冶样品中的钍

Separation and Determination of Thorium in Minerals and Metallugical Processing Products with Ion Exchange Paper by XRF Analysis

本文叙述了阳离子交换纸对钍的予富集、吸附条件及干扰情况。发现在保温条件下,静态吸附10分钟就可以获得分离富集目的。这样就大大简化了操作手续,缩短了实验流程;为钍的快速测定提供了简便方法。对含量为0.1%钍的样品,本法15次测定变动系数为3.26%。

A rapid and simple determination of thorium in minerals and metallugical processing products by XRF analysis is described.It is based on the use of ion exchange paper with static sorption for 10 minutes in 0.5-2.0 N hydrochloric acid.The coefficient of variation for sample containing 0.1%Th is 3.26%(n=15).The method can be used for determination of thorium within the range of 0.00x-x%.
