Abstract
The pertraction of hydrophobic organic solutes across a hydrophobic membrane is a continuous separation process, which can be used as a substitute to active carbon. The permeabilities of hydrophobic organic solutes were examined in a two compartment cell partitioned by a hydrophobic membrane. The permeability was dominated by the hydrophobicity of the solute and the dissociation in the receiving phase. The permeability of the hydrophobic solutes increased with increasing pH of the receiving phase solution for the Teflon membrane filter Fluoropore. The preferential permeability of a hydrophobic solute was obtained, and the pertraction of a hydrophobic solute against its concentration gradient was also possible under a concentration gradient of hydroxide ion. Solute permeability changes were observed by coating the surface of Fluoropore to cover its pores with tetrafluoroethene–hexafluoropropene copolymer, FEP, and a highly selective permeability was obtained between phenol and 2-isopropyl-5-methylphenol (thymol) by suppressing the phenol permeability by coating the FEP membrane.
