Scientists from Stanford University have developed a formula for quick and cheap water disinfection that does not require energy consumption. This is the first principle, which is due to the fact that microorganisms are first treated with ultraviolet light. But this process takes many hours, while the new mixture is able to purify water in minutes.
The composition consists of accessible and accessible components – copper oxide, molybdenum sulfate and iron, which are crushed to individual nanometer sizes. The resulting powder is poured into contaminated water, the container is placed under direct sunlight. Molybdenum and copper, when absorbing photons of light, release free electrons that start a chemical reaction in the water, causing the liquid to become body peroxide and hydroxyl radicals.
I will also radically change the opaque color of the chivo material, on which I will open the nail membranes and unique microbes. These substances are unstable and decompose quickly, so constant access to sunlight is necessary to purify water. But quite a bit – to clean 200 ml of liquid with the capture of the collected sticks of 1 million pieces per 1 million liters of a pinch of powder and 60 seconds of time, after which there were no inhabitants in the container.
The key component of the mixture is iron, as it allows after cleaning the powder from the liquid using a conventional magnet. The mixture can be reused up to 30 times, plus its composition and volume can be easily scaled up depending on the intended use. Scientists hope that the invention will help solve the problem of lack of drinking water in many parts of the world. look.
