Alpha spectroscopic analysis of actinides (Th, U and Pu) after separation from aqueous solutions by cation-exchange and liquid extraction
(2010)The radioactivity concentration of 236Pu, 232U and 228Th in aqueous samples has been determined by means of alpha spectroscopy after chemical separation and pre-concentration of the radionuclides by cation exchange and ...

The effect of physicochemical parameters on the separation recovery of plutonium and uranium from aqueous solutions by cation exchange
(2010)The effect of physicochemical parameters such as pH, salinity (e.g. [NaCl]) and competitive cation (e.g. Ca 2+ and Fe 3+) concentration on the separation recovery of plutonium and uranium from aqueous solutions by cation ...

Selective separation of radium and uranium from aqueous solutions by Chelex-100
(2012)The affinity of Chelex-100 for radium has been investigated as a function of pH and salinity compared to the Chelex-100 affinity for uranium to assess possible application of the resin for the selective separation of the ...

Simplified alpha-spectroscopic analysis of uranium in natural waters after its separation by cation-exchange
(2010)A relatively rapid, economic and robust procedure is described for the alpha-radiometric analysis of natural waters. The analysis is performed by alpha-spectroscopy after pre-concentration and separation of uranium by ...
