Soybean-Based Graphene Filter
Researchers have come up with a way to create graphene from soybeans, a method cheaper and quicker than the ones known. This could also make the world’s strongest material more commercially viable.
Australian scientists have been able to create clean water with a new filter made from soybean-based graphene film.
This new filter is very effective and it can even make the dirtiest water drinkable, according to experts. It is also simpler, cheaper and more environmentally-friendly than other known methods.
The filter is called Graphair and is made from a graphene film with microscopic channels that trap pollutants while letting clean water through.
Scientists at the Commonwealth Scientific and Industrial Research Organisation (CSIRO) also developed a graphene-based film which is cheaper and more environmentally-friendly than typical graphene.
This could have positive implications for the 2.1 billion people who are known not to have access to clean, safe drinking water. Researchers have even used the system on the water in the Sydney Harbor, saying it came out clean enough to drink.
Unlike other filters, Graphair does not require a series of steps to get water clean but GraphAir transforms soybean oil, a renewable, natural material, into graphene films in one step.
