Abstract
A process for destroying CS.sub.2 in soil by alkaline oxidation by controlledly combining reagents with CS.sub.2 -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 CS.sub.2 -contaminated soil and caustic at a rate to prevent volatization of CS.sub.2. Off-gas produced by CS.sub.2 oxidation is collected and oxidized. The end product soil has substantially all of its CS.sub.2 oxidized.
