等速电泳法同时检测 Cl^-,NO_3^-,SO_4^(2-)和 F^-

Simultaneous Determination of Cl^-,NO_3^-,SO_4^(2-)and F^- by Isotachophoresis

本方法以 Ca^(2+)为前导配对离子,改变了 SO_4^(2-)的有效淌度,从而实现了 Cl^1,NO_3,SO_4^(2-)及 F^-的同时分离检测。分析结果与离子色谱法基本相符。

The effective mobility of sulfate ion was changed by using calcium ion as the co- counter ion of leading electrolyte.Chloride,nitrate,sulfate and fluoride ion were separated and si- multaneously determined.The results obtained from ITP agreed well with those obtained from IC.
