Activated Charcoal 5280 sq. ft. surface / per gram

[mdvaden]

Anyone ever used activated charcoal? Last time I used it was at a country club.

I was reading tonight to double check something I heard on television to make sure it was right.

One gram of Activated Charcoal / Carbon, has surface area exceeding 5000 square feet per gram.

Activated Carbon / Charcoal

No wonder its so useful when the need arises.

Did you spill something? What else would you use it for?

You can amend soil with it. I know it is useful for "holding on to stuff". Must be because of the high surface area and it's negative ionic charge (many macronutrients have a net positive charge). This can also make a case why organic material in the soil is so important.

How long will the soil stay ammended without the buffeting capasity reclaiming the area?

Sounds interesting. I'll bring it up in class on thursday.

Activated Charcoal has a high "cation exchange capacity (CEC)". As mentioned previously, many plant nutrients (really elements) have a negative charge, and things with a high positive charge can then hold onto nutrients to prevent leaching down through the soil. Organic matter is high in CEC, as is clay. The added bonus of organic matter is that it influences soil structure as well, which can be more important than simply soil texture (amount of sand, silt and clay). That's what makes organic matter so special.

Activated charcoal is being looked at now as a carbon sink. See biochar.org for an interesting concept.

Pretty sure its used in water filters. And our fish tank filter has it.

At country clubs, there were some small spills of herbicide on or near golf greens.

From what I understand, it could be useful for dealing with Casoron, where Casoron should not have been. Like a lady who called once, after "fertilizing" her lawn with Casoron by accident. And the neighbors for a favor.

The sod had to be cut and removed, and the activated charcoal applied to the surface soil.

The local turf supply company carries it.

Here is a quote from one article online...

Activated charcoal (or carbon) can reduce herbicide contamination in specific areas (gardens, greenhouses, lawns, etc.) and can also be used as a root dip to protect transplants (tomatoes, peppers, strawberries, ornamentals, etc.) from triazine or substituted urea herbicides. Activated carbon can also be used to “clean up” pesticide spills.

Other herbicides that carbon can deactivate include trifluralin (Treflan), bromacil (Hyvar X), benefin (Balan), bensulide (Betasan and Prefar), DCPA (Dacthal), dichlobenil (Casoron or Norosac), EPTC (Eptam), 2,4-D, terbacil (Sinbar), and chloroacetamide herbicides such as metolachlor or dimethenamid.

Activated carbon, used in a wide range of applications in diverse industries, is made by heating or chemically treating organic matter to create a porous structure. This gives a large surface area within a relatively small volume. Most activated carbon products are purified by acid and water washes to remove impurities and are available in both granular and powdered form. Charcoal for outdoor grills and the like cannot be ground up to achieve the same pore structure characteristics of activated charcoal on a pound-for-pound basis.

I LOVE charcoal. It is the only thing that I've found to cure a stomach ache in just a few minutes. Just put some in a glass of water and drink it. It works. It will get food poisoning like noone's business. The only thing to watch is if you have ulcers don't take it because it's a powder it can inflame them and certain perscriptions it will absorb. Works good to brush your teeth too. I know people who have pulled the poison out from brown recluse and black widow bites with a charcoal pultice (flax meal& water mixed with charcoal on a paper towel. You don't want charcoal in direct contact with an open wound because it will tattoo you. No harm but don't look good. (unless you wan't it) BOO YA!

You reminded me of another use.

Our son left his daypack on the floor and it had chocolate chip cookies it one pouch. Our Chihuahua got into it and ate maybe 4 cookies.

The vet made our dog ingest something that had activated charcoal, to absorb some of the toxins from the chocolate.

when I was in the army and we did week long or longer exersices, we had to make our self some charcoal for poising. Does work great but hard as heck to get down and stay down.
