New method removes micropollutants from water

A team of MIT researchers has developed a new way to clear pollutants from water, even when present in extremely low concentrations. (Learn more about their novel method: news.mit.edu/2017/electrochemi...)

The Massachusetts Institute of Technology is an independent, coeducational, privately endowed university in Cambridge, Massachusetts. Our mission is to advance knowledge; to educate students in science, engineering, and technology; and to tackle the most pressing problems facing the world today. We are a community of hands-on problem-solvers in love with fundamental science and eager to make the world a better place.
The MIT UA-cam channel features videos about all types of MIT research, including the robot cheetah, LIGO, gravitational waves, mathematics, and bombardier beetles, as well as videos on origami, time capsules, and other aspects of life and culture on the MIT campus. Our goal is to open the doors of MIT and bring the Institute to the world through video.

As my old Transition Metal Chemistry professor used to say, "The color is colorless, not clear."

[@Kangaroos_News]

First grade English teacher smacks him on the hand: "The water has no colour, it is clear".

[@barkfeld]

Breakthrough! Great job MIT.

[@Tracks777]

Great content. Keep it up!

[@nobocks]

Thank you MIT !

[@JorgeGamaliel]

Very very interesting!!

[@roidroid]

If this can be tuned, perhaps the principle could also be used as a small & very simple form of chemical analysis, like a *gas chromotograph* (ie: an artificial nose for sniffing things to find out what they are made of).
Coz if you can tune this system to selectively remove materials - then it can also selectively SENSE the presence of those same materials by simply measuring how much of the material has collected on the electrode.

yall need to invent a new way to extract nutmilk

[@SRIMAN2021]

very fruitful te theology. This technology is very suitable so iam interested to instal in Nepal.

[@joshuamartyn3987]

can't you just pass the water through activated fine carbon to achieve the same effect of purification, then pass it through a mesh and then filter paper? I'm genuinely asking, cause (as some people call it) 'activated' carbon adsorbates impurities and even neutralises odours, so why can't it do the same in water, if passed through a sand bed for filtration after the carbon and the filter paper, shouldn't the water that comes out after the process be ok to drink?

I love you guys.

Can someone explain to me what are faradaic materials ? I would like to make simpler version of this in a science fair.

[@rRobertSmith]

Isn't it in the the wiki already?

[@yutuniopati]

Can it remove salt ?

[@the_7th_sun]

most likely

[@umnikos]

Cool, but it's sort of slow.
Can it remove plastic nanoparticles too?

[@dosluke]

since it said organic, i doubt it.

[@dosluke]

cool

[@dosluke]

so my organic spinach has plastic in it? XD

[@mahobaby8766]

are you a fuckign moron? why are you watching these videos if u are?

[@yogatanaya6833]

i want a master degree in computer science in here someday :D

[@paulofilho_tv9271]

i will study there in 3 years remenber me

[@4fsfilms328]

jogos br Graal Acho que não cara kkk

[@paulofilho_tv9271]

Fourth Fantasy Studios BEM eu vim pros estados unidos aqui pra estudar ganhei bolsa 100% aqui em boston,mit e apenas outra meta

[@nicholaslandolina]

This is BS the faradaic material would glow... It's just the glow material timing out not being uv charged

[@rRobertSmith]

Since the glow material changes chemically to a no glow configuration ....your reason is faulty. A more interesting question is how would you know when your reactive plates are loaded down and full, since they don't appear to change much. (Probably put them in a cleaning pool and reverse the current.)

[@WilliamKelley1982]

great news is use a screen and drink the water don't worry about making nuclear radiation poison by trying to clean the water

[@anamikasinha6446]

Wow

[@harinimanikandan4821]

😢😮

[@firebird95driver]

It COULD help in third world countries, but where's the money in that??

[@comedyeffect273]

Things such as these should be used for the good of mankind and NOT for the wallets of some CEO somewhere.

[@dmelleis]

✌

[@erikm9768]

Looks like high school chemistry, could we really not think of this until 2017?
