离子色谱法测定水中阳离子的影响因素

Factors Affecting the Determination of Cations in Water by Ion Chromatography

文章对万通930型离子色谱仪同时测定水中Li^+、Na^+、Mg^2+、K^+、Ca^2+5种阳离子含量的影响因素进行了探讨,重点介绍了色谱条件、仪器维护、标准曲线校准和操作过程等因素对测量结果准确性的影响。确定了实验的最佳条件,所测定的结果接近标准值。

In this paper,the influencing factors of determination of Li^+,Na^+,Mg^2+,K^+,Ca^2+in water by Wantong 930 ion chromatograph are discussed,and the effects of chromatographic conditions,instrument maintenance,calibration of standard curves and operation process on the accuracy of measurement results are mainly introduced.The optimum experimental conditions were determined and the results were close to the standard values.
