Abstract

The separation of L,D-2-(3-chlorophenoxy)propionic acid mixture has been resolved by using capillary electrophoresis in capillary zone electrophoresis (CZE) mode. The wavelength detection was at 230 nm. The use of 50mM sodium dihydrogen phosphate buffer added with 10mM P -CD at pH 8.36 together with different applied voltage (to, 15, 20 kV) at a temperature of 30°C have been investigated. The results showed chiral separation of 2-(3 chlorophenoxy)propionic acid has been partly resolved by using 50mM sodium dihydrogen phosphate (PH 8.36) with 10mM P -CD at 30°C at 10, 15, 20 kV. Unfortunately, further attempts to improve the resolution of the mixture could not be performed in this study due to limited amount of CD and non-availability of other potential chiral selectors. Beside that, persistent capillary electrophoresis technical problems were encountered during this study.
