示波极谱法快速测定金属镁中微量镍

Rapid Oscillopolarographic Determination of Trace Nickel in Metallic Magnesium

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－ＴｒｉｔｏｎＸ－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.
