to deal with the environment of heavy metal materials also belong to the world first.
Graphene oxide is a kind of from the preparation of natural graphite and structure similar to that of carbon nano material with carbon nanotubes.Hou Shifeng told journal china graphite of science and technology press, activated carbon, carbon nanotubes and graphene materials for low concentration wastewater containing lead adsorption ability, graphene on the adsorption quantity of lead oxide as high as 800 mg/g, far higher than that http://nolimitstv.dk/content/china-graphite-0 of activated carbon 60 to 120 mg/g;At the same time, the oxidation of graphene has extremely strong regeneration, repeating the adsorbed/cycle after the adsorption capacity of only 5 to 10% drop.
Graphene oxide why has such a strong adsorption capacity of heavy metals?For two reasons: one is the oxidation of graphene is a single atomic layer thickness of the two-dimensional structure of nanometer materials, the specific surface area of up to 2600 square metres per gram theoretically, of all the carbon nanotube is one of the biggest;The second is in the process of the preparation of chinagraphiteprice.blog.com graphene oxide, http://chinagraphiteprice.blog.com/ its surface to form a large amount of active groups such as carboxyl, carbonyl, hydroxyl, epoxy group, etc.Therefore, oxidized graphene has an excellent adsorbent need the most basic elements: enough large specific surface area and high enough density of surface functional groups.
Hou Shifeng is introduced, the use of graphene oxide can lead the lead-acid battery industry wastewater emission concentration from now reduced to 1-100-1000 parts per 10 PPB, lead recovery rate increased http://www.mojakarijera.com/node/38894 to 95% - 99%, than the existing technology to reduce environmental emissions by 90%.The reporter understands, the results can effectively promote the cadmium, nickel, arsenic, copper, chromium, radioactive elements graphite manufacturers and other heavy metal graphite price pollution system, http://michaelkors888.unblog.fr/2015/07/21/graphite-material-suppli... has the very considerable economic benefits and social benefits.
