A study on factors influencing the stability of colloidal liquid aphrons in predispersed solvent extraction of succinic acid |
초록 |
A key factor that influences the extractability in the predispersed solvent extraction (PDSE) is the stability of colloidal liquid aphrons (CLAs). The stability of CLAs is important in application of CLAs to the reactive extraction of succinic acid in fermentation broth. CLAs were formulated from a TOA/1-Octanol solvent phase. Trioctylamine (TOA) was used as extractant and 1-Octanol was used as diluent. Water soluble surfactant for preparing CLAs was sodium dodecyl benzene sulfonate (SDBS) and oil soluble surfactant was Tergitol 15-S-3. Stability of CLAs was measured by UV spectrophotometer. In this work, the effect of composition of organic solvent was measured to optimize solvent composition in column PDSE, and the effect of pH and ion species of continuous aqueous phase was investigated for application to fermentation broth. |
