摘要: The possibility of humic acids acting as micellar phase in electrokinetic chromatography was evaluated. We investigated the separation naphthalene capillary electrophoresis using various samples under different pH conditions, concentrations acid, and temperature. acid studied were from origins including peat, vermicompost a commercial sample acquired Aldrich. Methanol used marker for electroosmotic flow. results indicate that formation micelle depends on number nature hydrophobic association sites an aqueous solution origin concentration at defined pH. At lower values, molecule forming pseudomicelles increases due to combination neutralized dissociated charged sites.
