摘要：

A new approach to radiochemical separation of Fe-55 in waste waters of the Krsko Nuclear Power Plant (hereafter referred to as the NPPK) is described. The proposed sensitive, fast and simple method is based on the preconcentration of radionuclides present in the liquid sample with ammonium pyrrolidinedithiocarbamate (APDC). The precipitated carbamates were separated by filtration through a cellulose-nitrate filter and the thin deposit obtained on the filter was then measured by an X-ray spectrometer. The activity of 55Fe was determined from a calibration procedure which utilized a certified solution of this radionuclide. (C) 1999 Elsevier Science B.V. All rights reserved.
