| 摘 要： | 本文用盐酸溶解样品，火焰原子吸收光谱法测定电解金属锰中K，Na,Ca,Mg,Fe，石墨炉原子吸收光谱法测定其中的Cr,Cu,Co,Ni含量。对测定条件进行了实验，找出最佳溶样方法和酸度，对共存元素的干扰有排除亦进行了试验，获得了满意的效果。该法简便、快速、准确，加标回收率为88.9%-108.7%之间，相对标准偏差为0.6%-6.7%，标准曲线法、标准加入法结果与对照结果相吻合，适用于电解金属锰样品金属杂质元素的分析。

| Abstract: | The content of K, Na, Ca, Mg, Fe in electrolytic manganese are determined by FAAS, and content of Cu,Cr,Co,Ni determined by GFAAS after sample is dissolved by HCl (aq). The best condition for determination is investigated,including method of dissolving and acidity, and influence of coexist elements and exclusion of these influences. The methods prove to be rapid,accurate and convenient. The recoveries of method are 88 9%-108 7%, the relative standard deviations are 0 6%-6 7%. The results obtained by calibration curve method are in good conformity with the standard addition method and results measured by ICP.The method can be utilized in analysis of impurities in electrolytic manganese. |
