摘要:

建立一种ICP-MS半定量分析坭兴陶样品的方法。该方法采用获得的质量-灵敏度曲线确定样品中存在的元素种类及大致含量范围。经与标准物质GBW07402对照,坭兴陶样品中的⁷Li、⁵¹V、⁵²Cr、⁵⁵Mn、⁵⁹Co、⁶⁰Ni、⁶⁵Cu、⁶⁹Ga、⁸⁸Sr、⁹³Nb、¹³⁷Ba、¹³⁹La、¹⁴⁰Ce等13种微量元素的含量范围为7~350mg/kg,分析准确度为±50%。

Abstract:

ICP-MS is used to conduct qualitative and semi-quantitative analysis of elements in Nixing china samples. The types and concentration range of elements in samples were detected. The results showed there were 13 elements including ⁷Li,⁵¹V,⁵²Cr,⁵⁵Mn, ⁵⁹Co, ⁶⁰Ni,⁶⁵Cu, ⁶⁹ Ga,⁸⁸Sr,⁹³Nb,¹³⁷Ba, ¹³⁹La and ¹⁴⁰Ce in Nixing china.The contents of elements were ranged from 7~350μg/g and RSD was±50%.
