摘要
应用原子吸收分光光度法(GB/T5009·13、14、90、92-2003),对10种生物性样品中的锰、铜、铁、锌、镁、钙6种矿物元素进行了重复测定,并同时测定2种标准参考物质来控制实验室分析的准确性。在结果的表达方式上,应用不确定度来评价生物样品中的矿物元素含量。结果给出了10种生物物质的6个矿物元素的含量分布,为其作为标准参考物质提供了基础数据。
The study is to evaluate the content of Mn, Cu, Fe, Zn, Mg and Ca in 10 sorts of biological material. The standard methods (GB/T5009.13,14,90,92- 2003) were taken to measure. Two standard reference materials were used to control the accuracy of analyses. And chemical uncertainty was used to evaluate 6 minerals content. The results described the six minerals contents for the ten biologic materials. The study provided the necessity conditions to be used as standard reference materials for these 10 biological materials.
