| Research Abstract |
A copolymer of sodium 2-(acrylamido)-2-methylpropane-sulfonate(NaAMPS) and sodium 12-methacrylamido-dodecanoate(NaMmD) was grafted on the polymer support, and the adsorption/ desorption behaviors of bisphenol-A(BPA), which is a representative hydrophobic endocrine disruptor, were examined. This polymer formed a micelle at pH below 10, and adsorbed BPA molecules. On the other hand, at pH above 10, the micelle disintegrated, and BPA molecules were desorbed. The BPA molecules were hold stably in the hydrophobic microdomain in the micelle, and the amount depended on the composition of NaAMPS and NaMmD, and the changing rate of the pH of the solution. From these results, the lodestar for the development of the separation system was obtained.
