| 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-H_2O_2,and then La,Ce,Y were determined by ICP-AES.The method is simple,rapid and accurate. |
