【摘要】 用碱熔地质样品,三乙醇胺掩蔽铁、铝,乙二醇双(2-氨基乙基醚)四乙酸(EGTA)络合钙、钡,经过滤用HCl-H2O2溶解沉淀,用水定容后以ICP-AES测定La、Ce、Y,此方法简便,准确。更多还原

【Abstract】 The geological samples were first fused with alkali.Triethanolamine and EGTA were used to cover iron,and aluminum and interact with calcium,and barium to from complexes,respectively.The filtrated residue was dissolved with HCl-H₂O₂,and then La,Ce,Y were determined by ICP-AES.The method is simple,rapid and accurate.更多还原
