It's called activated charcoal or activated carbon.

它叫做活性炭，或者活性碳。

These are removed at the help of activated charcoal filters aboard the station.

这些在空间站的活性炭过滤器的帮助下被移除。

The global market for activated charcoal is projected to reach 6.2 billion dollars by 2022.

到2022年，活性炭的世界市场预计将达到62亿美元。

The key to activated charcoal whether it's saving a life or depriving you of nutrition, is timing.

活性炭能否救人一命、是否会带着你的养分，关键在于使用它的时机。

Activated charcoal is used for medical poisoning emergencies only.

活性炭仅用于医疗中毒紧急情况。

Activated charcoal as a health trend is one of the stupidest things I've ever heard.

活性炭作为一种健康趋势是我听过的最愚蠢的事情之一。

Green coconut and activated charcoal cleansing balm.

绿椰子和活性炭清洁膏。

(laughs) - This is Salty Caramel Ash made with dry burn activated charcoal.

- （笑） - 这是用干烧活性炭制成的咸焦糖灰。

Adsorption means molecules bind to the surface of another compound, like the carbon-lined pores in activated charcoal.

吸附意味着分子结合到另一种化合物的表面， 例如活性炭中的碳内衬孔。

So activated charcoal has a huge surface area.

所以活性炭具有巨大的表面积。

Some people claim to get whiter teeth from activated charcoal toothpaste, but no one’s done research on it yet.

有人声称使用活性炭牙膏可以使牙齿更白， 但还没有人对此进行过研究。

And because activated charcoal has such a large surface area, there are plenty of places for poison molecules to bond.

而且由于活性炭的表面积很大， 毒分子有很多地方可以结合。

To make activated charcoal, also known as activated carbon, you treat charcoal with heat and oxygen, or with certain acids and bases.

要制造活性炭（也称为活性炭）， 您需要用热和氧或某些酸和碱处理木炭。

The difference is that activated charcoal is burned at a higher temperature so it breaks down into a very fine powder which gives it a larger surface area than a chunk of charcoal on your grill.

它们的区别在于活性炭的燃烧温度更高，所以木头能分裂成非常细的粉末，使得它的表面积比你烤架上的块状木炭要大。

So when a molecule passes through the tiny pores in the activated charcoal, those very weak charges make it cling to the carbon thanks to Van der Waals forces.

因此，当一个分子通过活性炭中的小孔时，由于范德华力， 那些非常弱的电荷使其附着在碳上。

Activated charcoal is good at collecting molecules that contain carbon, like most poisons, because they’re usually large enough and have enough electrons to have stronger Van der Waals interactions.

与大多数毒药一样， 活性炭擅长收集含碳分子，因为它们通常足够大并且具有足够的电子以产生更强的范德华相互作用。
