Abstract

Single-column ion chromatography (SCIC) for anion determination in drainage water and soil solution was tested. The SCIC minimum detection limits (100-microliter sample loop) were 0.75 mg l-1 for Cl-, 0.2 mg l-1 for NO2-N, 0.02 mg l-1 for NO3-N, 1.25 mg l-1 for HPO4-P, and 0.5 mg l-1 for SO4-S. The results showed a high reproducibility. Results for Cl-, NO3-N and SO4-S obtained by the SCIC method were compared with those obtained by traditional methods; Student's t-test and regression analysis showed that the methods agree closely.

摘要

对用于测定排水和土壤溶液中阴离子的单柱离子色谱法（SCIC）进行了测试。单柱离子色谱法的最低检测限（100微升进样环）为：氯离子（Cl-）0.75毫克/升、亚硝酸盐氮（NO2-N）0.2毫克/升、硝酸盐氮（NO3-N）0.02毫克/升、磷酸氢根磷（HPO4-P）1.25毫克/升、硫酸根硫（SO4-S）0.5毫克/升。结果显示出高重现性。将单柱离子色谱法获得的氯离子、硝酸盐氮和硫酸根硫的结果与传统方法获得的结果进行了比较；学生t检验和回归分析表明这些方法吻合度很高。
