Abstract
A highly selective, rapid, one-step radiochemical separation procedure for gold has been developed. It is based on the solvent extraction of gold diethyldithiocarbamate from a 0.01–10 N sulphuric or hydrochloric acid medium using a substoichiometric amount of copper diethyldithiocarbamate in chloroform. The separation has been applied to the determination of traces of gold by neutron-activation analysis in high-purity lead, the rock W-1, gold-doped semi-conductor-grade silicon and a biological material (kale). Amounts of gold down to 2 × 10 −10 g have been determined.
