【摘要】本方法以 Ca²⁺为前导配对离子,改变了 SO₄^2-的有效淌度,从而实现了 Cl¹,NO₃,SO₄^2-及 F^-的同时分离检测。分析结果与离子色谱法基本相符。更多还原

【Abstract】 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.更多还原
