| Abstract: | The electrophoretic behaviors of polylols in a solution of sodium tetraborate are investigated by the capillary electrophoresis with a laser-based interference refractive index detector. The effects of pH, concentration of sodium tetraborate and structure of polylols on the effective mobilities of polylols-borate complexes are discussed. A new method for the separation of polylols by high-performance capillary electrophoresis has been established. In a solution of 0. 075 mol/L sodium tetraborate .ethylene glycol ,propanetriol ,ery-thritol tsorbitol .mannitol and dulcitol were separated in about 12 min. |
