In science I read a article called “Banana Peels” It was a very interesting article I must say. The most interesting fact is that it said
Banana Peels – The New Water Purifier?
Now that got your attention, we all love bananas the only part we do not like is the peels so we just end up throwing them away, but what we do not know is that the banana inside does not have all the nutritions, the peel does and we all though that it has no use at all, but could this have an affect on banana peels?
There are banana peels that are ending up in water like in the oceans, rivers, lake etc. People may think that this is bad because of littering but scientists believe that banana peels can be the new water purifier. Ranging from use as a fertiliser to curing warts and even, polishing shoes and silver. Now it turns out, that it can even help remove heavy metals from water and just cleaning the water. The type of metals that are found in water are mercury (Hg), cadmium (Cd), arsenic (As), chromium (Cr), thallium (Tl), and lead (Pb). Heavy metals are natural components of the Earth’s crust. They cannot be destroyed. The discovery was made by Brazilian scientist and banana lover Gustavo Castro. The tests revealed the presence of nitrogen, sulfur and most importantly, organic compounds like carboxylic acids(an organic acid), that have the capability of binding with metals that they come in contact with.
How did the Scientist find out?
How the scientist found Gustavo Castro, and his colleagues did an experiment. To experiment if the acids in the peels would be effective in polluted water, Gustavo Castro and some colleagues added them to jars of water taken from Brazil’s Panama River, which is known to contain copper and lead. Not only did the peels perform better than existing purifiers like silica and carbon, but they also could be re-used eleven times in a row!, before they stopped working! In addition to that, they are low cost, can easily be found all over the world and, leave behind no chemical residue. The only bad thing is that they cannot kill bacteria.
Does it actually work?
Yes it does work, I tried this today and left the banana do its work.
This is how the banana looks like
when you put a banana in dirty water
And on the bottom is how the water looked like after the banana just stayed floating around and soaked all the dirty water, the only thing was left was bits and pieces of the banana’s inside floating around.
I tried drinking the water and I tasted really weird but it was still better than drinking dirty water
Will it affect the world?
This will affect the world because when you have dirty water you can purify it by just putting a banana in the water. This will affect the world because we can remove the heavy metals from the water. The way to remove heavy metals is by running water through a distiller by heating water to boiling and then collecting the steam that is released. The metals that filled the water do not evaporate with the steam but instead collect on the bottom of the distiller leaving the collected steam clean and clear. Then your remove the heavy metals with a filtration system. Then you install a revers osmosis system, This system removes heavy metals by passing water through a membrane and draining out the additives including heavy metals. This will also affect it environmentally because there are lots of dirty water and maybe if the banana peels can purify the dirty water. Countries like Africa have troubles getting water and the water they are getting could be dirty so maybe once a while we can put some banana peels inside and let it purity the water.
Is it Beneficial or harmful?
Ok so after reading this blog post you must be thinking, “hmmm yes he proved that it is safe but is it safe?” and after the article saying it works and me saying it is safe because I actually did it you should agree that this is beneficial. So in conclusion I think that this science is beneficial because this can solve many problems around the world such as places that has dirty water and if we put a banana peel it can give clean water to the countries that do not have clean water. And maybe clean up dirty rivers or lakes even though it will be hard maybe we can do this. Here is a good video that explains about banana peels being able to clean water, I think that this is enough evidence to say it is true.
This has been you host Mark and thank you for listening.
Words I do not understand
Fertiliser: a chemical or natural substance added to soil or land to increase its fertility.
Purifier: remove contaminants
