Reversible Adsorption/Desorption of Target Molecules with Novel Temperature-Sensitive Heteropolymer Gels

摘要

SSS-VBTA gel was synthesized with sodium styrene sulfate(SSS)and vinylbenzyl trimethylammonium chloride(VBTA).The SSS-VBTA gel was found to show the thermo-reversible changes in its volume and properties,that is,shrunken and hydrophobic state at around room temperature while swollen and hydrophilic state at above room temperature.It was revealed that the SSS-VBTA gel concentrated trace amounts of Bisphenol-A present in very dilute aqueous solutions at around room temperature and released the concentrated Bisphenol-A above room temperature.
