A basic study of the effect of the SDS on the behavior of the anionic surfact in electrophoresis was performed. Having been interacted with SDS micelle, long chain carboxylates and sulfonates which have more than 10 carbons have been suffered larger changes in their apparent mobilities. Based on the result of the comparison among apparent, electroosmotic and electrophoretic mobilities, it is demonstrated that the major cause for the variation of the apparent mobilities of the anions is the variation of the electrophoretic mobilities.
