Abstract
Methods and compositions for the remediation of environmental contaminants using redox reactions are described. The redox reactions include manganese compounds and peroxide generating compounds. The methods and compositions are also useful for the remediation of highly oxidized environmental contaminants.
Claims22
A process for remediation of a site having one or more soil contaminants, one or more groundwater contaminants, or a combination thereof, the process comprising the steps of contacting the site with (a) Mn(IV) or a composition capable of generating Mn(IV), and generating Mn(IV);
- (b) a buffered aqueous solution having a pH in the range from about 6 to about 10;
- and (c) a peroxide or a compound capable of forming a peroxide.
