Outline of Final Research Achievements |
This study evaluated the removal performance of a graphene oxide (GO) membrane for pharmaceuticals and personal care products (PPCPs). Negatively charged PPCPs exhibited higher rejection than neutral and positively charged PPCPs, indicating electrostatic repulsion is an important removal mechanism by the GO membrane. Adsorption can also be an important removal mechanism for neutral PPCPs by the membrane.

Academic Significance and Societal Importance of the Research Achievements |
ナノマテリアルを用いた新素材膜は次世代の水処理膜として期待されるが、その研究は未だ萌芽期であり、膜の除去性能は一部のイオン類に対する評価にとどまっていた。本研究では下水中に存在する多様な医薬品類を対象に、酸化グラフェン膜での除去特性を評価したものであり、新素材膜での微量化学物質の除去特性の解明につながるものである。
