摘要:
分别用碳酸根淋洗液体系和氢氧根淋洗液体系碱片-离子色谱法对硫酸盐化速率样品进行比对试验。结果表明,2种淋洗液体系在0.00~20.0 mg/L质量浓度范围内线性良好,标准曲线相关系数均>0.999,检出限、精密度、准确度和测定结果都没有显著性差异,说明这2种淋洗液体系方法是等效的。采用氢氧根淋洗液体系分析硫酸盐化速率,可配备淋洗液发生器,背景更低,实验操作步骤更少,工作效率更高,建议作为首选方法。

Abstract:
The samples of sulfation rate were analyzed by ion chromatography with carbonate eluent system and hydroxyl eluent system respectively. The results showed that the two systems exhibited a good linearity in the range of 0.00~20.0 mg/L, and the correlation coefficient of the standard curve could reach 0.999, and there was no significant difference in the detection limit, precision, accuracy and determination results. Carbonate eluent system ion chromatography and hydroxyl eluent system ion chromatography are two equivalent methods. The hydroxyl eluent system is recommended to be the first choice to analyze the sulfation rate for the eluent generator can be equipped to lower background, fewer experimental operation steps and higher work efficiency.
