Abstract

For the removal of endocrine disrupting chemicals (EDCs),
such as di-(2-ethylhexyl) phthalate (DEHP), from drinking water, we prepared beta-cyclodextrin
included polysulfone (PSf/CD) hollow fiber membranes. beta-Cyclodextrin (beta-CD) was modified
with fatty acid chlorides to produce amphiphilic beta-CDs. PSf/CD hollow fiber membrane was
prepared from polysulfone (PSf) dope solution with those amphiphilic beta-CDs by phase inversion
process. In the membrane formation process, the amphiphilic beta-CDs migrated to the membrane
surfaces via hydrophilic-and hydrophobic-mediated self-assembly. The performances of PSf/CD
hollow fiber membranes were measured and the results showed that PSf/CD hollow fiber membranes
can effectively remove DEHP from aqueous solutions and provided good water permeability. (C) 2012
