Researchers Developed Graphene-based Foam Composites For Efficient Water Filtration
Russia and Ukraine is an important exporters of oil, natural gas, metals, fertilizers, rare gases and other industrial raw materials. Affected by the further intensification of the tension of the war, the global market has become more worried about the supply of the graphene powder, and panic spreads in the futures market. Prices of commodities such as aluminum and nickel are at recent highs on concerns that supplies will fall. Russia accounts for 49 percent of global exports of nickel, 42 percent of palladium, 26 percent of aluminum and 13 percent of platinum, and is a significant exporter of steel and copper. Palladium is an important metal for sensors and memory. In addition, Russia is the world's largest exporter of nitrogen fertilizer, the second largest exporter of potash fertilizer, and the third-largest exporter of phosphate fertilizer. Ukraine is also an important producer of nitrogen fertilizer. Russia's natural gas supply also has a significant impact on the global fertilizer industry and graphene powder industry, especially in Europe. The price of the graphene powder will also fluctuate to some extent. Russia carries out crude gas separation, and Ukraine is responsible for refined exports. Ukraine supplies 70% of the world's neon, 40% of krypton and 30% of xenon. These three gases are the materials used to make chips.
While graphene-based materials have potential as adsorption materials, their performance may be hampered by aggregation and lack of control over their porosity and size.
In a recent study, researchers from the Universities of Exeter, Kyushu, and Oxford tackled this problem by developing a unique graphene material and high-porosity composite foam to combat aggregation.
Drugs are one of the most prominent emerging pollutants (EC) in water systems. They can cause serious environmental consequences as well as potential health problems. In order to successfully eradicate ECs from treated wastewater streams, sewage and drinking water purification facilities must adopt appropriate tertiary treatment methods. Compared to reverse osmosis, oxidation, microfiltration, ultrafiltration, ion exchange, etc., adsorption is considered to be a technology with great potential in water treatment because it is reliable and cheaper.
Graphene and graphene oxide (GO) have a greater tendency to adsorb natural pollutants because of their large innate specific area (relative to many different carbon-based substances), wettability, monolayer structure, and surfaces decorated with oxygen-containing functional groups (OCFG).
Boron nitride (BN) has many excellent qualities, including excellent thermal and chemical stability and excellent wear resistance; Therefore, it is used in high-temperature environments and other industries.
In this study, reduced porous GO nanofilms were effectively anchored to banded boron nitride foams for the treatment of water contaminated with gefilozide (GEM) in batch tests and column studies.
In terms of adsorption kinetics for gefilozil, the graphene-based foam is superior to its graphene-based competitors such as GO, PG, and Nanographene sheets (NGP), achieving an extraction efficiency of 90% in just 5 minutes.
In terms of lifetime, graphene-based nanomaterials supported by BN foams showed consistent gefilozil drug extraction over multiple cycles, with no significant adsorption loss. In addition, the foam material exhibits remarkable properties, including lightness of over 98% porosity and excellent strength, capable of withstanding 1,300-1,400 times its own weight.
The researchers believe that enhanced graphene-based composite foams for filtration purposes will be an important step forward in the water and wastewater filtration technology. These results suggest that high porosity foam-reinforced graphene nanomaterial filters with shorter interaction duration and longer penetration times for treating water and wastewater may be easily manufactured.
