摘要: The separation of alkanesulfonate (RSO 3 - ) and alkyl sultate (ROSO 2 surfactants by capillary electrophoresis (CE) is dependent on the butter cation its concentration. Divalent cations increased migration time resolution to a greater extent than that monovalent cations. As additive concentration increases, anion surfactant increases. effect due change in electroosmotic flora which occurs because exchange between weakly acidic silanol surface silica wall
