Isotachophoretic determination of stability constants of Ho and Y complexes with deithylenetriaminepentaacetic acid and 1,4,7,10-tetraazadodecane-N,N´,N´ˇ,N´ˇˇ-tetraacetic acid
Original language description
The method of capillary isozachophoresis with conductivity detection was applied for the determination of the physico-chemical characteristics (conditional stability constants log Bˇ) of holmium and yttrium complexes with DTPA (diethylenetriaminepentaacetic acid) and DOTA (1,4,7,10-tetraazadodecane-N,Nˇ,Nˇˇ,Nˇˇˇ-tetraacetic acid). The log Bˇ determination is based on the linear relation between the stability constants of lanthanide-DTPA (lanthanide-DOTA) complexes and the reduction of the zone of the complex owing to the bleeding phenomena (liberating free metal ion). The stability constants calculated using this relationship are comparable with the literary data obtained by other methods for both holmium (log BˇHo-DTPA=21,9, log BˇHo-DOTA=24,5) and yttrium complexes (log BˇY-DTPA=21,2 log BˇY-DOTA=24,4). Capillary isotachophoresis was applied for the determination of the optimum composition of the reaction mixture (metal:ligand ratio) as well.
