Abstract  

The X-ray spectrometric method for uranium determination in sea water is discussed. Two techniques of uranium enrichment are presented: (1) precipitation with the chelating agent ammonium-1-pyrrolidine dithiocarbamate (APDC) in the presence of iron(II) as a carrier and (2) complexation with APDC followed by adsorption on activated carbon. The best pH range and the other optimized conditions for uranium determination in sea water with both methods are reported.
