Abstract

A method was developed to determine of Fe,Ti,Mg,Mn,Zn,Cu,Pb,As,Cd,Ni,Cr,Co,Sb,Al and Ba in the quartz sand by inductively coupled plasma-atomic emission spectrometry(ICP-AES).The effect of the HF-HClO4 and HF-H2SO4 digestion systems to the results was investigated.Moreover,the conditions of acid consumption,digestion temperature and instrumental conditions were optimized.The detection limits for the elements were 0.17-0.88 μg/g and the recoveries of the method were 90.4%-110.7% with RSD(n=6) of less than 5.0%.The method possesses the advantages of simple operation,high sensitivity,good precision and is suitable for routine analysis of impurity elements in the quartz sand.
