How Activated Charcoal Works. Activated charcoal absorbs a wide variety of drugs and chemicals. Adsorption is a process in which atoms and molecules move from a bulk phase (such as a solid, liquid, or gas) onto a solid or liquid surface. In other words, the toxic substance attaches to the surface of the charcoal.
Alternatives to Charcoal. Some people use live moss instead of charcoal. Live moss will help absorb odors in a terrarium and has the added benefit of absorbing excess water that leads to root rot and odor. You may find lush, green, growing moss more attractive than a layer of charcoal.
