According to experimental results, the extraction capacity of 1H,1H,2H,2H-perfluoro-1-octanol is acceptable with distribution ratio (D) of 13. The extraction efficiency reaches 98.0% after three stage continuous countercurrent extraction under the conditions of pH 2.55-3.16 and temperature 20-25 degrees C at oil to water (V-o/V-w) ratio of 1. The residual of 1H,1H,2H,2H-perfluoro-1-octanol in aqueous phase was quite low, which was less than 2 ppm. The back-extraction of 1H,1H,2H,2H-perfluoro-1-octanol by NaOH was demonstrated to be feasible, which is up to 100% with single stage. (C) 2015 Elsevier B.V.
