Abstract

The effectiveness of degradative solidification/stabilization with ferrous iron (DS/SFe(II)) that combined contaminant degradation by Fe(II) and immobilization by cement hydration products has been proven to various CAH. Batch tests for transformation of 1,1,2,2-TeCA were performed in cement slurries containing Fe(II). 1,1,2,2-TeCA was completely and rapidly transformed to trichloroethylene (TCE) within < 1 hr in the Fe(II)/cement system. A linear relationship described the relationship between the pseudo-first-order rate constant for TCE disappearance and Fe(II) dose up to a dose of 196 mM. The maximum value of the rate constants occurred ∼ pH 12.1 at Fe(II) dose of 196 mM in 10% cement slurries. Degradation rates for TCE showed a saturation relationship with initial target organic concentration for concentrations between 0.01 and 1 mM. This is an abstract of a paper presented at the 231st ACS National Meeting (Atlanta, GA 3/26-30/2006).
