摘要：

The extraction system ammonium tetramethylenecarbodithioate/isobutylmethylketone is applied to the simultaneous preconcentration of the toxic trace elements As, Cd and T1 from soil digests at an acidity of 2-3 mol/l sulphuric acid and to their separation from the major soil components. The extraction procedure is easily coupled to AAS. The accuracy of the method is checked by the analysis of a certified reference material. RSD is between 4 and 10%.
