Researchers From Australia Discovered A Quick And Inexpensive Way To Clean Toxic Water
Having safe drinking water is an important human necessity. One of our best advancements in technology has to be how we get our clean, safe water. The most common way nowadays is with a filtered pitcher. But what can be done about water that is considered toxic?
Researchers at the University of New South Wales in Sydney, Australia have found a revolutionary way to clean toxic water using a filter made of aluminum oxide. During the course of their experiments, they found that when a piece of aluminum is dropped into room-temperature gallium dozens of sheets of aluminum oxide are quickly produced.
They also found that using the sheets allowed them to filter heavy metal ions and oil contamination from water at incredible speed.
Professor Kourosh Kalantar-Zadeh, the team leader of the project, believes that this inexpensive method of creating aluminum oxide can lead to creating cheap and portable filters, possibly helping those who lack access to clean drinking water.
The professor believes these revolutionary filters may help people in Africa and Asia, where heavy metal ions in water exist in great quantity.
Before the team at UNSW Sydney found a new method for creating aluminum oxide, the process was time-consuming and took incredible amounts of energy and super-heated aluminum to produce.
Although far more expensive than the aluminum, gallium can be reused to produce the substance. When water makes contact with the surface of the gallium, aluminum oxide comes to the surface. Interestingly enough, because it does participate in the reaction the liquid can be used again and again.
Kalantar-Zadeh also says that this manufacturing process is so cost-effective, producing water filters this way can be done out of a household kitchen.
The professor and his team released the concept as public domain so others may use it to help improve everyone’s quality of life.
