玄武岩是生产玄武岩纤维的原料，玄武岩中二价铁和三价铁的含量对纤维的性能有很大的影响。建立了电感耦合等离子发射光谱法（IC P‐O ES ）和重铬酸钾滴定法同时测定玄武岩中总铁和二价铁的分析方法。对ICP‐OES优选了适宜的仪器测定参数和分析谱线。结果显示ICP‐OES具有较高的准确度，相对标准偏差为2.2％，加标回收率为98％～101％。用该方法测试玄武岩中的总铁和二价铁可得到准确结果。

Basalt is the raw material of basalt fiber .The content of FeO and Fe2 O3 has a great impact on the properties of basalt fibers .ICP‐OES and dichromate method were used to test total Fe and Fe2+ in basalt .Suitable instrument parameters and analy‐sis lines of Fe were chosen for ICP‐OES .The relative standard deviation (RSD) of ICP‐OES is 2.2% ,and the recovery is in the range of 98% ~101% .The method shows simple ,rapid and highly accurate for determination of total Fe and Fe2+ in basalt . The RSD of ICP‐OES and dichromate method is 0.42% and 1.4% ,respectively .
