Abstract: Either copper(II) diethyl dithiocarbamate or zinc diethyl dithiocarbamate was applied as a reagent for the substoichiometric extraction of gold to its activation determination in iron. The separation was carried out either by the well-known direct substoichiometric extraction of gold or by the substoichiometric reextraction of the Au(DDC)2Cl compound from the medium of ethyl acetate into diluted hydrochloric acid. The gold in iron was determined over the concentration range 0.04—0.2 μg/g.
