Title:
METHOD AND APPARATUS FOR REMOVAL, SEPARATION AND RECOVERY WITH HIGH EFFICIENCY USING POROUS HYDROPHOBIC FILM BY USING HYDROPHILIC AND HYDROPHOBIC PROPERTY CHANGE DUE TO DISSOCIATION OF PROTON DISSOCIATION COMPOUND AQUEOUS SOLUTION
Document Type and Number:
Japanese Patent JP2013132595
Kind Code:
A
Abstract:
To provide a method and an apparatus which are capable of energy-saving separation, removal and recovery, that is, separating and recovering products in the synthetic industry, and removing environmental contaminants, and the like, by a simple principle and apparatus.
A compound containing a proton dissociation group is protonated in the condition of pH<pKa (dissociation constant) and exhibits high hydrophilic properties, and is deprotonated to provide an essential hydrophobic properties at pH>pKa. Therefore, two kinds of water phases having different pH's are separated with a porous hydrophobic film using hydrophilic-and-hydrophobic-property change depending on pH.
