We proposed capillary zone electrophoresis(CZE)for identifying metal ions(Mg2+, Ca2+, Mn2+, Fe3+, and Zn2+)in the common ice plant(Mesembryanthemum crystallinum L.)using complexation with trans-cyclohexane-1,2-diaminetetraacetic acid(CyDTA). Analytes in an extract from the common ice plant were detected simultaneously and were separated from coexisting substances. However, analytical results obtained using the proposed procedures did not agree sufficiently with those obtained using inductively coupled plasma atomic emission spectrometry(ICP-AES). Results suggest the potential usefulness of the proposed method, but further study must be conducted to improve the method.
