摘要
应用火焰原子吸收光谱法对液氨中的铁含量进行测定。分析了测定条件。方法简便、快速。测定铁的线性范围为 0～ 8.0 0mg/L ,相关系数为 0 .9999。应用于样品测定 ,测定结果的相对标准偏差小于 2 % ,加标回收率为97.4 %～ 10 6 .1%。
Iron in liquid ammonia was detemined by flame atomic absorption spectrophotometry with analyzing determining conditions. The method is simple and rapid. The linear range is 0～8.00 mg/L with the correlative coefficient of 0.9999. The method was applied to the determination of iron in liquid ammonia, the recovery is 97.4%～106.1% with RSD being less than 2%.
