amine 추출제가 포함된 Colloidal Liquid Aphrons (CLAs)의 안전성 |
| 초록 |
An Aphron is defined as a distinct unit of fluid, encapsulated by a thin soapy film of another fluid. This soapy film enables polyaphrons containing amine extractants to be dispersed in the pregnant phase without mechanical mixing. Therefore, a conventional mixer-settler stage can be eliminated and energy saving can be accomplished by comminuting only one phase instead of both copper-bearing solutions and organic phase containing amine extractants. The stability of Colloidal Liquid Aprhons (CLAs) in the continuous phase is related with removal of Cu(II) in Predispersed Solvent Extraction (PDSE). In this study, PDSE of Cu(II) according to the concentration of SDBS was performed. The amine extractants used were trioctylamine(TOA) and trioctylmetylammonium chloride(Aliquat 336). The stability of CLAs was also investigated. |
