Remediation of DDVP-contaminated soil by surfactant

摘要：

　　Sodium dodecyl sulfate is selected to eliminate contaminated soil which is polluted by diethyl dichlorovinyl phosphate.This article discusses the effects of temperature,contact time and liquidsoil ratio for the efficiency of elution by means of experiment and aim at determining the optimum experimental conditions.The results indicate that the elution efficiency of diethyl dichlorovinyl phosphate increases with the increasing of sodium dodecyl sulfate concentration,liquid soil ratio,temperature,and extraction time within a certain range.The elution efficiency could achieves the maximum 36% while the concentration of surfactant is 15000 mg/L,temperature is 30°,contact time is 10 hours and liquid-soil ratio is 30:1.
