| 摘 要： | 酸溶碱融溶解铍铀伴生矿石中的铍,加入的焦硫酸钾对ICP-OES法测定存在基体干扰。本研究主要阐述消除基体干扰的一些措施。从实验数据可知,控制称样量、焦硫酸钾加入量、定容体积和加标稀释倍数,能够有效消除焦硫酸钾对ICP-OES法测定结果的基体干扰,测定结果的相对标准偏差为3%-5%。

| Abstract: | Thawing dissolved uranium associated ore of beryllium in acid soluble alkali, existing matrix interference added potassium pyrosulfate determination method of ICP-OES. This research mainly discusses some measures to eliminate the matrix interference. From the experimental data, control said Coke potassium sulfate addition amount, sample volume, constant volume and spiked dilution, can effectively eliminate the matrix interference potassium pyrosulfate determination results of ICP-OES method, the relative standard deviation is 3%-5%. |
