Beijing, August 13 (Xinhuanet) the banana is delicious and nutritious, but most people may not know, it is " a bundle of negatives " to seem to be Banana skin last function when some is magical,for example it is have, last silverware,etc. not to last skin. In addition, the banana peel and heavy metal pollutant in the all right adsorbed water. The researchers of the university of St. Paul state of Brazil find, the banana skin minced can remove heavy metal such as harmful copper, lead in the drinking water effectively. The aqueous cleaning apparatus made of banana peel, even use for 11 times continuously, it is still prominent that it absorbs characteristic that heavy metal pollutes. Researchers think, the skin of banana can purify the field to play an important role in water quality, because compared with purification method that adopts at present, this method not only environmental protection is cheap, and the durability is better. Influenced by the industry of mining and metallurgy and pollution of industry and agriculture, the content of heavy metal of much regional drinking water exceeds standard, detrimental to health seriously. Deal with the heavy metal to pollute by daily chemical method in the past, namely add medicine and heavy metal into water and react, but this kind of method is not only with high costs, medicine used but also may be harmful. So, it is a present difficult problem of scientific research to develop cheap high-efficient water quality and purify the method. ? Say at researcher publication in American Chemical Society " industry and project chemistry are studied ", besides banana peel, research shows before this, some plant waste material such as the coconut and shell fiber, peanut shell can also be regarded as good water quality and purified materials.
