文摘
Portland cement activated the persulfate anion in soil, at doses from 0.25% to 5.0% (by weight).
Even low persulfate doses (below 1.5%) oxidized a significant portion of contaminants.
The reduction in contaminant leachability was proportional to contaminant oxidation.
Combined oxidation and stabilization reduced leachability far more than stabilization alone.
