| 摘 要： | 参考GB/T 5009.12—2010标准方法,采用石墨炉原子吸收光谱法测定了螺旋藻中铅的含量。实验结果表明,铅的线性关系良好(R≥0.999 5),标准样品GBW10025测定值与标准值吻合,样品加标回收率测定数据良好(回收率92.6%),同时验证了前处理过程中赶酸操作和基体改进剂选择的重要性。方法方便可靠,数据准确,适合测定螺旋藻中铅的含量。

| Abstract: | Lead content in Spirulina and GBW10025 were measured by Graphite furnace atomic absorption method with GB/T 5009.12-2010 as the reference. The results showed that the relationship of the lead element was good(R=0.9995), And the measurement value of the standard sample matched the cetified value of GBW10025. The recovery rate was higher than 92%. At the same time, Pre-treatment of removing acid and selection of matrix modifier were verified to be important. The method is convenient and reliable with accurate data. It is suitable for measuring lead content in Spirulina. |
