APPLICATION OF HIGH-PRESSURE LIQUID-CHROMATOGRAPHY IN INORGANIC ANALYSIS .5. REVERSED-PHASE CHROMATOGRAPHY OF METAL DIETHYLENEDITHIOCARBAMATES AND TETRAMETHYLENEDITHIOCARBAMATES

The possibilities for reversed-phase HPLC of metal dithiocarbamates have been systematically examined. Beside the diethyldithiocarbamate chelates examined also included are the tetramethylenedithiocarbamates. The diethyldithiocarbamates of Pb, Ni, Co, Cu and Hg and the tetramethylenedithiocarbamates of Cd, Pb, Ni, Cl, Zn, Cu and Hg are suitable for this technique and have proved separable from one another. All other metal chelates of these groups are decomposed in the chromatographic system, give asymmetrical peaks or because of low retention unresolved bands. The results from the reversed-phase chromatography are discussed and compared with previously described separations using thinlayer adsorption chromatography and gas chromatography. © 1979 Friedr.
