Daily we pour in drains not only waste his life, but also particles of various medicines. At the end of 2019, it became known that from-for hits of chemical elements in the water some species of fish become less mobile, causing more risk of becoming victims of predators and in the end unable fully to die. Even more damage to animals and nature in General, applied antibiotics, which are used not only in medical purposes but also for growing plants and accelerate the growth of livestock. Scientists already know how to decompose trapped in water antibiotics by using cerium metal, but this chemical element is also harmful to the nature. Fortunately, recently the Russian and Chinese scientists were able to solve the issue.
About a new way of wastewater treatment from antibiotics was described in a scientific journal Scientific Reports. As a rule, antibiotics used to treat infections caused by pathogenic bacteria. However, in addition, they are widely used in agriculture to prevent diseases in animals and plants, and accelerate their growth. Due to the high frequency of using antibiotics in large quantities get into the water and harm the health of fish and other living organisms.
How drugs harm the environment?
Very popular in agriculture use of antibiotics of the tetracycline group. Their popularity is due to the comparative low cost and broad spectrum of activity, but they do not decompose in water for a very long time. To speed up this process uses the so-called catalysts, which are substances that increase the rate of flow of chemical reactions. For the decomposition of antibiotics is great, the metal is cerium, but it in itself is very harmful to nature. It would be great if it performs its function without getting in the outdoors?
Fortunately, scientists from Russia and China thought to introduce cerium ions in the crystal lattice of Apatite, which is a known mineral. Mostly it is already contained in the bone tissue of living organisms calcium phosphate, therefore, completely harmless to the environment. In experiments, scientists have found that the crystal lattice of the mineral does not allow the catalyst to reach the water, but it allows you to speed up the decomposition of antibiotics.
According to the candidate of chemical Sciences Dina Deineko, thanks to their design can not only purify water from antibiotics, but also to identify them even the slightest presence. And the thing that cerium, in addition to their catalytic properties, is also a great indicator of antibiotics.
