[Feng] Chen, Qingrui Geng, Hang Lu, Helen WillcockHelen Willcock, Qiuming Liu, Fangyingkai Wang, Kaidian Zou, Ming Jin, Hongting Pu, Jianzhong DuThe efficient removal of trace carcinogenic organic pollutants, such as polycyclic aromatic hydrocarbons
(PAHs) and ionic dyes, from water is an important technical challenge. We report a highly effective
recyclable multifunctional azobenzene (AZ)-based silica-supported polymeric adsorbent which can
simultaneously remove both PAHs and anionic dyes from water to below parts per billion (ppb) level based
on multiple interactions such as the hydrophobic effect, [pi]–[pi] stacking and electrostatic interactions, thus
providing a new strategy for designer water remediation materials.
