Essay

The thesis is devoted to a systematic investigation of complex formation salts of Ti(IV) and Zr(IV) with o-posphoric and hydroxyethylidenediphosphonic asids in aqueous solutions, in broad pH-range, at different constituent rations by means of polynuclear NMR (1H, 13C and 31P) and pH-potentiometry. The composition and structure of mono- and polynuclear complexes, wich formed in solution, have been established. It has been shown that a mixture of these acids can be used in the syntethis of titanium and zirconium-based sorbents.
