Table 3 Membrane rejection in different solvent systems
From: Pharmaceutical concentration using organic solvent forward osmosis for solvent recovery
Solvent | Draw solution | Feed solution | Solvent flux (LMH) | Rejection (%) |
|---|---|---|---|---|
Ethanol | 2 M LiCl | 2000 ppm Tetracycline | 2.65 ± 0.30 | 99.0 ± 0.5 |
Isopropanol | 2 M LiCl | 2000 ppm Tetracycline | 0.36 ± 0.15 | 99.2 ± 0.2 |
Hexane | 50% Methyl palmitate | 20% Triglycerides | 1.35 ± 0.17 | 98.2 ± 0.6 |
