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