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-HCl04 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.关键词
