A process for the remediation of soil containing volatile organic compounds which comprises the steps of: (1) forming an emulsifier comprising: (a) from about 70 to about 99 % by weight of a sugar surfactant selected from the group consisting of an alkyl polyglycoside, a glucamide, and mixtures thereof; and (b) from about 1 to about 30 % by weight of a nonionic surfactant, other than said sugar surfactant which, when combined with said sugar surfactant, provides a hydrophilic- lipophilic balance of from about 8.0 to about 13.0; (2) mixing said emulsifier with said unwanted contaminants to form a stable emulsion; and (3) removing said stable emulsion from said soil.
L'invention concerne un procédé pour restaurer un sol contenant des composés organiques volatiles consistant à (1) former un émulsifiant contenant (a) entre environ 70 % et environ 99 % en poids d'un tensioactif glycosidique, choisi dans le groupe des alkyl-polyglycoside, glucamide et de leurs mélanges; et (b) entre environ 1 % et environ 30 % en poids d'un tensioactif non ionique, autre que le tensioactif glycosidique en question qui, quand il est combiné avec le tensioactif glycosidique, donne une valeur de balance hydrophile-lipophile dans la plage allant d'environ 8,0 à environ 13,0; à (2) mélanger l'émulsifiant avec des contaminants indésirables pour former une émulsion stable; et à (3) débarrasser le sol de l'émulsion stable.
