This avoided a banana peel over because it can make you slip, but now the experts found that banana peel could prevent materials pollute water pollutants. Results of previous studies show coconut fiber, peel peanuts, and other plant materials are able to move harmful toxins, such as lead and copper from water.
Mines, factories and farms can produce potentially harmful waste and environmental health. The newest method to purify water of heavy metals is still very expensive, even some of the materials used for the purification process also has poison.
Scientists at the University of Sao Paulo Brazil, and colleagues conducted a study to determine whether a banana peel can also purify water. Banana peel can also be used to polish silver and leather shoes.
Banana peels consist of atomic nitrogen, sulfur and organic materials such as carboxylic acids. These acids can bind to the metal that is in the water, said Gustavo Castro, a researcher from the University of Sao Paulo.
The researchers found pieces of banana peels can remove lead and copper from river water in Parana, Brazil. According to them, the purification of banana peels can be used up to 11 times. Synthetic materials can be used several times, but the natural ingredients are much cheaper and does not require a chemical process to make it.
