| Abstract |
A continuous liquid-liquid extraction system (CLLE) for concentrating trace organics from water into methylene chloride for analysis was designed, built and evaluated. The CLLE uses Teflon coils for phase contact and gravity phase separation. The system includes a self-contained excess solvent distillation chamber, so the methylene chloride is recovered and recycled. The units are portable, and are currently in service sampling raw and treated water at locations in the northeastern United States. |
