Abstract:Single-columnionchromatography (SCIC) for cation determination in drainagewater and soilsolution was tested. Using a 100-μl sample loop, the SCIC detection limits were 0.04 mg l−1 for Na+, 0.02 mg l−1 for NH4-N, 0.06 mg l−1 for K+, 0.05 mg l−1 for Mg2+, and 0.085 mg l−1 for Ca2+. Results were highly reproducible in wide ranges of concentrations. Results obtained by the SCIC method were compared with those by atomic emission spectrometry (Na+ and K+) and atomic absorption spectrometry (Mg2+ and Ca2+). Student's t-test and regression analysis showed that corresponding methods agree closely.
