I assume you mean activated charcoal's filtering effects. This is because activated charcoal has an enormous surface area. For example, 1 gram of activated charcoal has the surface area of roughly 2 tennis courts. This amount of surface area allows for impurities to be trapped and absorbed by the charcoal, giving it its filtering effect.

well its carbon... so the carbon... heres why...
Activated charcoal is carbon that has been treated with oxygen. The treatment results in a highly porous charcoal. These tiny holes give the charcoal a surface area of 300-2,000 m2/g, allowing liquids or gases to pass through the charcoal and interact with the exposed carbon. Because adsorption works by chemically binding the impurities to the carbon, the active sites in the charcoal eventually become filled.

Its not a substance. Charcoal is extroadinarily porous. All the little pores are like little holding cells. What goes in, never comes out. It doesnt really neutralize poison but it traps it. IT more to do with the physical shape of the charcoal than a chemical interaction.

It is not a substance in charcoal, it is the charcoal itself, which is mostly carbon. It absorbs poisons, not neutralize. It is not antibacterial.

Charcoal is just charred wood. Since the wood is burnt, it is lighter weight, more absorbent and less dense.

They adsorb toxins thus reducing the harm done.
