The development of decentralized household filters is one of the most feasible solutions for treating As(III)-contaminated groundwater worldwide. To avoid the health risks caused by premature breakthroughs, it is vital to design a robust filter to intensify the effective contact between active sites and trace As(III). Herein, we have developed a filter filled with a flexible adsorbent that can continuously change its configuration under the shear force of a flowing fluid to actively enhance mass transport, wherein bimetallic Fe/Zr nanoparticles...
