Metal-filtering sponge removes lead from water

Science Daily  May 11, 2023 In recent years great strides have been made to design adsorbents to detoxify water, as well as for a related challenge of recovering valuable metals at low concentrations. However, applying nanomaterials at scale and differentiating which nanomaterials are best suited for particular applications can be challenging. Researchers at the Northwestern University have developed a methodology for loading nanomaterial coatings onto adsorbent membranes, testing different coatings against one another, and leveraging these materials under a variety of conditions. The tailored coating for lead remediation, made from manganese-doped goethite nanoparticles, could filter lead from contaminated water to […]
