Usually applied in situ, chemical oxidants (such as peroxide, ozone, sodium, potassium permanganate, sodium persulfate and sodium percarbonate) can be injected into the ground where they interact with and break down organic pollutant molecules into harmless substances like carbon dioxide and water.
Traditionally, sodium persulfate has been used and activated with the addition of a separate component such as heat, chelated metals, hydrogen peroxide, or a caustic base.
ARS applied a combined treatment to the subsurface consisting of an oxidant, Klozur([R]) sodium persulfate, activated with PermeOx Plus([R]), a time-release calcium peroxide-based catalyst designed to accelerate the aerobic bioremediation of hydrocarbons.
Last year, in a major scientific breakthrough, VeruTEK scientists were able to stabilize plant surfactants with various oxidants including sodium persulfate and hydrogen peroxide.
VeruTEK is using stabilized catalyzed hydrogen peroxide in three of its technology platforms: S-ISCO(TM), which effectively targets and removes organic contamination in soil and groundwater, SEPR(TM) (Surfactant-Enhanced Product Recovery), and nanoscale zerovalent metal applications, which are used as catalysts for hydrogen peroxide and sodium persulfate.
