A Novel Micellar Electrokinetic Chromatographic Method for Separation of Metal-DDTC Complexes

Figure 5

Electropherogram of five metal ions obtained using 25 mM borate buffer of pH 9.1 containing CTAB (30%, 100 mM) and organic modifier (butanol) in ratio of (70 : 30 : 5 v/v/v). Conditions: capillary, fused silica 52 cm (effective length 40 cm), i.d. 75 mm, applied voltage −10 kV at reverse polarity, hydrostatic injection 4 sec. UV-VIS detection at 225 nm, capillary temp, 25°C.
