[Terrapreta] Using Activated Charcoal to Inactivate Agricultural Chemical Spills

[Mark Ludlow]

Hi Erich,

 

Can you postulate how the carbon distinguishes from "good" molecules and
"bad" molecules?

 

Best,

Mark

Inactivating Pesticide Spills


"If a pesticide is spilled accidently, if the wrong pesticide is applied, or
if a pesticide is applied at an excessive rate, the best solution is to
apply a material that will adsorb or inactivate the pesticide. Once the
pesticide has been adsorbed, it is biologically inactive and cannot cause
environmental contamination by running off in surface waters or leaching
into groundwater. Activated charcoal (activated carbon) is the universal
adsorbing material for most pesticides. Powdered activated charcoal is made
up of very small carbon particles that have a high affinity for organic
chemicals such as pesticides. Activated charcoal has a large surface area to
which organic molecules can bind. When it is applied to
pesticide-contaminated soil, the pesticide molecules are attracted to the
charcoal particles and bind to them when they come into contact"

"Activated charcoal is manufactured by many companies, such as ICI Americas,
Inc. and West Virginia Pulp and Paper Company. It is available through your
local agricultural chemical dealer. Two commonly used agricultural carbons
are Gro-Safe (ICI Americas) and NuChar S-A (Westvaco). Activated charcoal
usually costs about $1 per pound or less."


Hi All, 
I thought this was pertinent  to the post concerning  biochar  &  Roundup  a
few weeks ago.

I thought I would send the above Activated charcoal producers a post  to
make sure they were apprised of the current progress in TP soils technology
in hopes to get them interested.

Cheers,
Erich
