Separation and determination of emetine dithiocarbamate metal complexes by capillary electrophoresis with chemiluminescence detection of the tris(2,2'-bipyridine)-ruthenium(II) complex.
Emetine dithiocarbamate metal complexes, which were prepared from emetine, carbon disulfide, and metal(II), indicated large chemiluminescence intensities on tris(2,2'-bipyridine)-ruthenium(II) chemiluminescence. Capillary electrophoresis with chemiluminescence detection was developed for analyzing emetine and the metal complexes. After the optimization of various analytical conditions, the mixture of the Cu(II), Ni(II), and Co(II) complexes as a model sample was injected into the capillary electrophoresis system with chemiluminescence detection. They were successfully separated and detected with a detection limit of 50 nM.
