Methods of decreasing the amount of one or more contaminants in contaminated soil comprise introducing polymer-coated nanoparticles into the contaminated soil, op-tionally with other reagents. The polymer-coated nanoparticles exhibit an enhanced ability to migrate through the soil and pro-vide greater control of the rate of activation of other chemicals, such as oxidants, in the contaminated soil.

L'invention concerne des procédés de réduction de la quantité d'un ou de plusieurs contaminants dans un sol contaminé, consistant à introduire des nanoparticules revêtues de polymère dans le sol contaminé, éventuellement avec d'autres réactifs. Les nanoparticules revêtues de polymère présentent une capacité améliorée de migration dans le sol et permettent un meilleur réglage de la vitesse d'activation d'autres agents chimiques, par exemple des oxydants, dans le sol contaminé.
