Thin-layer chromatographic behaviour of some heavy metal-diethyldithiocarbamate complexes has been studied using calcium carbonate, calcium citrate, calcium oxalate, calcium phosphate dibasic, calcium sulphate dehydrated, cellulose and silica gel G as stationary phase and acetonitrile, acetone, benzene, butanol, chloroform, 1,4-dioxan, distilled water, ethyl acetate, EDTA-ammonia buffer (1:1), methanol and propanol as mobile phase. Cd(H) and Pb(II) from Mn(II), Fe(III), Co(II), Ni(II), Cu(II), Hg(I) and Hg(II) have been practically separated on cellulose impregnated with sodium diethyldithiocarbamate in ethyl acetate.
