Use of Capillary Zone Electrophoresis and Micellar Electrokinetic Chromatography for Separations of Anthraquinone Derivatives

Original language description

The behavior of seven hydroxy anthraquinone derivatives was studied by capillary zone electrophoresis and micellar electrokinetic chromatography. The effects of buffer pH (6.5 - 10.8) and sodium dodecyl sulfate concentration (10 - 20 mmol L-1) on the effective mobilities of the analytes and their separation were tested. A comparison of the two optimized separation systems showed that micellar electrokinetic chromatography was superior as it permits separation of all the seven analytes within 15 mins., using 15 mmol L-1 sodium dodecyl sulfate in 10 mmol L-1 tetraborate buffer, pH 8.5, at a voltage of 20 kV. The calibration curves were linear in the concentration range from 5.0.10-7 to 5.0.10-4 mol L-1 for most of the analytes, at a detection wavelengthof 254 nm. LOD and LOQ values of the analytes were in the ranges of 2.10.10-7 - 1.28.10-6 mol L-1 and 6.99.10-7 - 4.25.10-6 mol L-1, respectively.
