Abstract
Procedimento per la rimozione di sostanze idrocarburiche da terreno contaminato da tali sostanze che comprende:a) il trattare il terreno contaminato da sostanze idrocarburiche con una soluzione acquosa di surfattina con un rapporto percentuale (peso/peso) surfattina/terreno compreso tra 0,01 e 0,2%; e b) il separare il terreno decontaminato dall'emulsione olio/acqua contenente la surfattina.Il procedimento, che può essere effettuato "in situ" oppure "on-site", consente di ottenere una buona rimozione dei contaminanti utilizzando concentrazioni di surfattina inferiori rispetto a quelle impiegate con un tensioattivo convenzionale.
