Sažetak
Within the study of 166Ho-complexes as potential radiopharmaceutical agents, stability constants of those with EDTMP (ethylenediamine-N,N,N´,N´-tetra(methylenephosphonate)) were calculated by the computer program LETAGROP Etitr using data from potentiometric titrations measured at 25 °C in 0.1 M NaCl. The following values were obtained for stability constants of Ho-EDTMP complexes Ho(OH)L6–, HoL5–, HHoL4–, H2HoL3–, H3HoL2– and H4HoL: log β = 9.31, 20.22, 28.14, 34.55, 39.89, 45.05, respectively. Diagram of the complex speciation dependence on pH shows that complex forms HHoL4– and H2HoL3– are characteristic of the pH range 6–8, which is adequate for their application into the human body.
