摘要

Feldspar samples were digested with HCl-HNO₂-HCLO₄-HF mixed acids and K, Na, Ca, Mg, Al, Ti and Fe in sample solutions were directly determined by Inductively Coupled Plasma-Atomic Emission Spectrometry （ICP-AES）. The results were in agreement with the certified values and chemical method. This method provided the advantages of wide dynamic linear range, high efficiency and simple operation. The method has been applied to determine these components in various feldspar samples with accurate and reliable results.
