| 摘 要： | 本文首次研究高浓度盐基体中，大量盐的存在对无机阴离子的保留时间，峰高峰面积等参数的影响规律，并对其影响机理进行了初步探讨，实验证明，在样品中离子总浓度不超过柱容量孤情况下，虽然由于某些离子的浓度过高，使待测离子的保留时间变短，峰形改变，但用峰面积和标准加入外推法计算，仍可得到较即的结果。

| Abstract: | This paper studied the effects of large amounts of salts in the simulative matrices on the retention time, peak height and peak area for analysis of anions by ion chromatogra-phy ,and the mechanism was preliminarily explored. The experiments show that the samples with high concentration of some anions cause a relatively shorter retention time and a changed peak shape, but a better result can be obtainded by measurement of peak area and standard spike.Recoveries of various inorganic anions in tap water were 95. 5%, 96. 8% and 95. 2% for chloride, nitrate and sulfate, respectively. |
