| Abstract: | The contents of Ca,Mg,Fe,Al in micro-silica,which was digested by HF,HNO3,HClO4,and were determined by ICP-AES,simutaneously.The recoveries were 95.2%—100.3% for Ca,96.2%—99.6% for Mg,95.8%—97.2% for Fe,98.6%—104.6% for Al.The relative standard derivation was from 1.50%—2.59%.This method shows low detection limit of metals,high analysis efficiency,good accuracy and precision,and can determine the contents of Ca,Mg,Fe,Al in micro-silica quickly and correctly. |
