Rezumat

The metal ions separation by chromatographic techniques, using dialkyldithiophosphoric acids (HDADTP) as extracting agents is presented in this paper. The mechanism of extraction chromatography is briefly described. The separation mechanism of metal ions by TLC using HDADTP is a complex process based on adsorption-desorption, cation exchange and extraction, the later ones being dominantly. The nature of organic mobile phase containing HDADTP plays a decisive role in extraction chromatography of metal ions, especially for lanthanides and actinides.
