| Abstract: | This study was about the extraction of Rhodamine B and methylene blue in the aqueous two phase system of SDS/CTAB/H 2O/NaBr mixture. It was found that the surface electrical charge of material had an important influence on its distribution coefficient. The material with positive charge in solution could be easily extracted by aqueous two phase system with excessive anionic surfactant,while negative charged material could be easily extracted with excessive cationic surfactant. |
