    This new filter removes 99% of toxic heavy metals in water

    Source: Author: Time: 2017-07-28 Views: Times

    Scientists have developed a new filter made of carbon nanotubes and quartz fibers that purifies 99% of this type of heavy metals. More importantly, they can be reused.



    The new filter uses quartz fibers as a substrate, then places carbon nanotubes on them and treats them with an oxidant. The final step is to give the material super metal immersion properties. The filters are tested in the laboratory to treat water samples contaminated with cadmium, cobalt, copper, mercury, nickel and lead. This filter is capable of treating 5 liters (1.3 gallons) of water in less than a minute, then washing it with vinegar in 90 seconds and using it again. This step does not affect the performance of its immersion metal. Because the raw materials required for the filter are cheap, 1 gram of this material can treat about 83,000 liters of contaminated water and meet the standards of the World Health Organization, which will be enough to meet the daily needs of 11,000 people.
