Appeal No. 1996-0270
Application 08/118,128
Appellant claims a method for decontaminating soil which
contains an organic compound having at least one oxidizable
aliphatic or aromatic functional group, by contacting the soil
with a recited ferric chelate and a peroxide compound in the
presence of water at the pH of the soil. Claim 1 is
illustrative and reads as follows:
1. A method for decontaminating soil containing an
organic compound having at least one oxidizable aliphatic or
aromatic functional group comprising contacting the soil with
an active, soluble ferric chelate selected from the group
consisting of ferric nitrilotriacetate and ferric
hydroxyethyleniminodiacetate and a peroxide compound in
amounts effective to achieve oxidation of the soil
contaminating compound in the presence of water at the pH of
the soil.
