    摘要: The present invention is a method for the detoxification and/or chemical remediation of soil contaminated with volatile organic compounds. The process comprises treating the soil with the sodium and calcium salts of naphthalene sulfonates, lignosulfonates, their derivatives and mixtures thereof. The volatile organics are then forced from the soil as the soil is more attracted to the admixture than it is to the volatile organic contaminants.
