以铁灯作光源-火焰原子吸收法测定饮用水中微量锰

Flame Atomic Absorption Method Using Iron Lamp as Light Resource for Determination of Trace Manganese in Drink Water

探讨了以铁空心阴极灯作光源 ,火焰原子吸收法测定饮用水中微量锰。结果表明 ,本法相对标准偏差为 4 1 2 % ,加标回收率为 96 0 %～ 99 7% ,用本法对质控样进行测定和对比试验 ,结果令人满意 ,同时实现了一灯多用。

A determination of trace manganese in drink water by flame atomic absorption method using iron lamp as light resource has been investigated.The result shows that the RSD is 4 12%,the recovery is 96 0%～99 7%.The method is satisfactory.
