电谱-离子色谱和电谱-流动注射分析联用的研究

Study on Combination of Electrography and Ion Chromatography and Flow Injection Analysis

电谱和低压离子色谱的联用可以对固体试样进行快速地定性定量分析 ,使用该技术对合金钢中铬的含量进行分析 ,发现当CrO42 -离子浓度在 10 -6～ 10 -3 mol/L时有良好的线性关系和高的精密度 ,结果与常规化学分析方法相符。这项技术也可以应用于合金中铜、锌。

The combination of electrography and low pressue ion chromatrography can quickly analyze solid samples .Using this technique to determine the centent of chrome in Alloy steel, it is found that there is an excellent linearity and high precision when the concentration of CrO 4 2- is 10 -6 ～ 10 -3 ?mol/L. The result is consistent with that of normal chemistry analysis methods. This technique can be used to analyze the content of cuprum ,zinc ,aluminum etc in alloy and biospecimen.
