		Russia's clean water revolution: new technology costs low, no chlorine and ozone According to the Russian satellite network, Russian scientists have proposed using graphene to disinfect water. In 2010, Russian scholars Andrei Heim and Konstantin Novoselov had won the Nobel Prize for the preparation of graphene materials. Experts believe that the cost of new technologies is not high and can gradually become the basis of the world's water purification standards. According to reports, the new characteristics of graphene were discovered by researchers at the Moscow State Institute of Iron and Metallurgy (NUST MISIS), a researcher at the National University of Russia, and colleagues at Tambov National University and Saratov State University. Researchers have recently confirmed that graphene oxide can clean heavily contaminated water. This discovery is enough to revolutionize the field of centralized water supply. At present, industrial water purification is completed with strong oxidants, such as chlorine, ozone, and sodium hypochlorite. Their toxicity is very strong, so tap water needs to be boiled, clarified, and filtered before drinking. Graphene oxide is no more harmful to the human body than charcoal, and it can kill harmful bacteria like chlorine. In the experiment, scientists introduced graphene oxide into solution (medium and saline), which contained the most dangerous E. coli in the tap water source. The saline simulates water while the medium mimics the human body. Experiments have shown that graphene oxide completely destroys bacteria, and the residue accumulates in the form of floccules in solution, which can be easily removed with a mechanical filter, leaving water suitable for drinking. If the extract is treated with ultrasonic waves, graphene can be extracted and reused. Researchers believe that if the purification system is used for tap water, it is not necessary to add chlorine later. At the same time, the cost of disinfecting with graphene oxide is very low. Alexander Yeganov, a chemical engineer at the Center for Bioanalytical Research and Molecular Design (formerly the Central Chemical Toxicology Laboratory at the University of Chechenov), explains that although chlorine has always made great efforts to keep people away from the coliform, there are huge Poison, chlorine-containing tap water is still harmful to people; ozone toxicity is weak, but too expensive, it is not suitable for promotion. Anna Anziferova, director of the Innovation Technology and Nanomaterials Safety Laboratory at the Kurdatov Institute of the Russian National Research Center, believes that graphene oxide is currently not expensive to produce and will be cheaper in the future. She believes that the new technology has every reason to gradually sterilize chlorination and ozone out of the market.
