摘要：

A group of metals can be extracted from aqueous solution by using hexamethyleneammonium hexamethylenedithiocarbamate as the chelating agent and a mixture of 2,4-dimethylpentan-3-one and xylene as the organic phase. A description is given of a procedure for the determination of microgram and nanogram amounts of the nine metals silver, bismuth, cadmium, copper, nickel, lead, thallium and zinc in aqueous solution. The influence of a high content of iron and copper on the extraction is described.
