PurificationGraphene can be used as a barrier as it is impermeable to all liquids and gases. Poking microscopic holes into graphene enables water to flow through. This allows for a environmental friendly, energy efficient, and excellent method of water filtration and desalination. Graphene oxide is a thin membrane created by oxidizing graphite. It is impermeable to all fluids except for water. A graphene oxide membrane can separate liquids, gases, salt, and the most minuscule particles from water. Also, it is cheaper and easier to make than graphene. Many cheaper, efficient, and better water filters and desalinators is made possible by this graphene oxide membrane. It makes clean water more accessible all around the world. Graphene oxide membranes do not stop at filtering water. The membrane can be augmented to allow others liquids or gases pass through, making the membrane a universal filter for various substances.
Graphene oxide membranes can be used to filter the Earth's atmosphere. The membrane can be used to separate gases. Therefore, it can be used to filter carbon dioxide and other pollutants in the air. This will reduce air pollution and even global warming because the membrane can be used to filter greenhouse gases out of our atmosphere. |
