Abstract
A process for destroying CS2 in soil by alkaline oxidation by controlledly combining reagents with CS2-contaminated soil, preferably by first performing a caustic presoak with NaOH followed by stagewise addition of oxidant, preferably percarbonate, such that oxidative reagents mix with a uniform mixture of CS2-contaminated soil and caustic at a rate to prevent volatization of CS2. Off-gas produced by CS2 oxidation is collected and oxidized. The end product soil has substantially all of its CS2 oxidized.
Claims42
A method of remediating CS2 in soil by an in situ chemical reaction comprising:
- controlledly combining CS2-contaminated soil with an oxidizing agent without substantial contact with air such that CS2 contained in the soil is drawn proximal to said oxidizing agent sufficient to react chemically therewith;
- and
- further controlling the in situ chemical reaction to prevent substantial vaporization or combustion of the CS2 or CS2 by-products.
