Formation Constants of some Lanthanide Chloro- and Nitrato-Complexes using Ion Exchange Method

The distribution coefficient of some lanthanides such as europium, terbium and thulium was studied using inorganic ion exchangers, zirconium titanium phosphate and zirconium phosphate silicate. The separation studies were carried out from hydrochloric and nitric acid aqueous solutions. From th distribution coefficient data, the monochloride and mononitrate complexes stability constants were calculated.
