"Static potentiometry and UV-VIS spectrophotometry methods were utilised to determine the protonation constants of (10-[4-aminobenzyl(hydroxyl)phosphonylmethyl]-1,4,7,10-tetraazacyclo-1,4,7-triacetic acid) (DOTA(NH2)) and stability constants of holmium and yttrium complexes with DOTA(NH2). The DOTA(NH2) protonation constants of [HA] (log 1 = 12.7); [H2A] (log 2 = 21.4) and [H3A] (log 3 = 27.9) were experimentally determined by static potentiometry. The stability constants of Ho-DOTA(NH2) (log KHo-DOTA(NH2) = 18.0) and Y-DOTA(NH2) (log KY-DOTA(NH2) = 17.8) complexes were determined by UV-VIS spectrophotometry using the competitive reaction of the DOTA(NH2) ? metal complexes with Arsenazo III." .
