Abstract：Basalt is the raw material of basalt fiber. The content of FeO and Fe2O3 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 analysis 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.
