| 摘 要： | 建立了离子交换色谱-电感耦合等离子体质谱(ICP-MS)测定高纯钛中Mg、Cr、Fe、V、Mn、Co、Ni、Cu、Zn、Sr、Cd、Ba、Tl、Pb等痕量杂质元素分析方法,并对ICP-MS工作参数及条件进行了优化和选择.高纯钛用HF和HNO3溶解后进入离子色谱的阳离子交换柱,经HF(3+97)淋洗后,用HNO3洗脱,洗脱下来的溶液进入电感耦合等离子体质谱检测.方法的检出限在0.00099～0.85 μg/L之间,测定下限为0.0033～2.8 μg/L,各元素的回收率在90%～110%之间.利用本方法对纯度＞99.99%高纯钛样品的杂质元素进行分析,结果表明,其精密度和准确度均满足痕量分析的要求.

| Abstract: | A new method for the determination of trace amounts of elements Mg,Cr,Fe,V,Mn,Co,Ni,Cu,Zn,Sr,Cd,Ba,Tl,Pb in high purity titanium by ion exchange chromatography and ICP-MS was developed,and ICP-MS operating parameters and conditions were optimized.Titanium were digested with HF and HNO3.The digested sample solutions were injected into ion chromatography with a cation exchange column.Impurity elements adsorbed were elution with HF,and eluted with HNO3,after that it was determinated by inductively coupled plas... |
