摘要
提出了一个快速测定金属镁中微量镍的新方法。在Ni(Ⅱ)-丁二酮肟-NH3-NH4Cl-NO-2-TritonX-100体系中,不经任何分离手续,直接测定了金属镁中0.0000x%~0.0x%范围内的镍,结果良好。
A new method for the rapid determination of trace Ni in metallic magnesium was developed.In Ni(Ⅱ)-(DMG)-NH 3-NH 4Cl-NO 2--TritonX-100 system the Ni in the range of 0.0000x%-0.0x% in metallic magnesium has been determined without preseparation,and there sults are satisfactrory.
