Research on Application of Surfactants to the Remediation of the Soil Polluted by Heavy Metals

Application of surfactants to the remediation of the soil polluted by heavy metals has been proved to be a prospective soil remediation technology.Surfactant remediation technology and its influence factors,mainly including ion-type surfactant remediation,biological surfactant remediation and combined remediation and so on,in the remediation of the soil polluted by heavy metals are introduced,the research trend for present soil remediation on complexly polluted soil is on combined application of many remediation technologies,furthermore,the problems in soil remediation technologies are discussed.
