| Abstract: | Extraction of Cr~(6 ) was carried out using gravity separation phase liquid membrane technology with n-trioctylamine as carrier,kerosene as the membrane solvent and NaOH as stripping agent.Factors affecting the extraction and stripping efficiency of Cr~(6 ) were studied.Factors,such as pH of Cr~(6 ) solution,the concentration of surfactant,the NaOH concentration of stripping solution and so on are considered.Emulsification and demulsification could be eliminated in this process,thus the technological process is simplier. |
