摘要：

Conditions of the quantitative extraction of Co, Cu, Fe(III), Ni, Pb, V(IV), and Zn from solutions on cellulose filters in the form of pyrrolidinedithiocarbamates obtained in flow were found. The elements were determined on filters by X-ray fluorescence spectrometry. The detection limits were 0.1, 1.2, 0.4, 0.2, 0.2, 0.4, and 0.3 mug on the filter, respectively. The relative standard deviation of the results of the determination was no higher than 8% for the amounts of elements on the filter of 5-50 mug. The accuracy of the determination of elements by the proposed sorption-X-ray fluorescence method in river and sea water and in soil extract was verified by the added-found method.
