The contaminated water (colored water in vials) is drawn through the hybrid membrane by negative pressure; the heavy metal ions (red spheres) bind to the protein fibers in the process. The filtered water is of drinking quality. Credit: Graphics copyright: Bolisetty & Mezzenga, Nature Nanotechnology, 2016
Water pollution is one of today’s most serious global problems. A new water filtration system has been developed that is superior to existing systems at removing various toxic heavy metal ions and radioactive substances from water and can even be used in gold recovery. Prof. Raffaele Mezzenga’s hybrid filter membrane not only has an extremely simple structure, but uses low-cost raw materials, such as whey protein fibres and activated charcoal...
