摘　　要：地质样品用碱熔后,三乙醇胺掩蔽铁、铝,EDTA络合钙、钡,过滤后用HCI溶解沉淀,定容后用ICP-AES测定地质样品中的Hf和Sc,此方法准确性好,精密度高,RSD均小于5%,方法简便快速。The geological samples were first fused with Na202, triethanolamin and EDTA were used to cover iron, and aluminun and interact with calcium, and barium respectively so as to from Complexes. The filtrated residue was dissolved with HC1. The Hf and Sc in geology samples were determined by ICP-AES. The method is simple＇rapid and accurate.
