Abstract

Simultaneous determination of Ge,Sn,As,Sb and Bi under different hydride generation reaction conditions by ICPAES has been studied. The acidity for hydride generation reaction, selection of buffer solution and oxidizer, dynamic linear range, interference from coexistent elements and their elimination were studied. The detection limits of the method are 0.04 g/L for As, 0.07 g/L for Sb, 0.2 g/L for Bi, 0.8 g/L for Ge and 0.2 g/L for Sn. The method has been applied to the determination of these elements in national standard reference materials (soil, rock, drainage sediment) and the results are in agreement with the certified values.\=\=
