Application of Capillary Electrophoresis to the Separation of Rhenium Complex of 1,2,3-Trihydroxybenzene
Monatshefte für Chemie(2017)
摘要
A capillary zone electrophoretic method has been developed for a separation of a reaction mixture of a rhenium complex. The rhenium complex was synthesized in a reaction of a rhenium precursor and 1,2,3-trihydroxybenzene in acetonitrile with triethylamine addition. The capillary electrophoretic method has been used for the separation in borate and phosphate buffer (pH 6.30–11.80). All components in the reaction mixture (unreacted precursor, ligand, and final rhenium complex) have been determined by capillary zone electrophoresis with UV–Vis detection in an aqueous running electrolyte within 10 min. Dependencies of effective electrophoretic ion mobility on the pH value have been determined for the ligand, unreacted precursor, and final complex in both electrolytes.
