Investigation of bis(carboxymethyl)dithiocarbamate complexes by the extraction method.


The extraction of copper, lead, cadmium, nickel and zinc dithizonates was investigated in the presence of ammonium bis(carboxy-methyl)dithiocarbamate. For all metals studied, except zinc, masking of extraction was observed, depending on the amount of the dithio-carbamate in the aqueous phase. From the shift of the pH(1 2 ) values for dithizonate extraction… (More)
